19880: drivers/ft5x06: fix initialization if callback function parameter is NULL r=aabadie a=gschorcht

### Contribution description

This PR fixes the `ft5x06` driver initialization if the callback function parameter `cb` is `NULL. This might be the case for example if the application uses the touch device in polling mode.

If the interrupt pin is initialized if the callback function parameter `cb` is `NULL`, the driver crashes the first time an interrupt is triggered. Therefore, the INT pin must be initialized only if also the callback function parameter `cb` is not `NULL`.

To be able to test the polling mode, this PR also includes a change of the `tests/drivers/ft5x06` application which introduces the environment variables `FT5X06_POLLING_MODE` `FT5X06_POLLING_PERIOD` and in the makefile.

### Testing procedure

1. Use any board with a FTXXXX touch device and test it in polling mode, for example:
   ```
   FT5X06_POLLING_MODE=1 BOARD=stm32f746g-disco make -C tests/drivers/ft5x06 flash term
   ```
   It should work as expected.
   ```
   main(): This is RIOT! (Version: 2023.10-devel-119-g92a44a-drivers/ft5x06_fix_cb_null)
   FT5x06 test application

   Released!
   ```

2. Checkout master branch and cerry-pick commit 691a5e6308426ddc685e5a2c297238529211c258. The test application `tests/drivers/ft5x06` will crash once a touch event occur:

bf720c0b41 drivers/ft5x06: configure interrupt mode in any case
The interrupt mode has to be configured independent on whether the INT pin is initialized already by the `ft5x06_init` function if parameter `cb` is defined or later, for example by the `touch_dev` implementation.

ca6760047c drivers/ft5x06: introduce coordinate conversions
To obtain coordinates from the touch panel that correspond to the display coordinates, it is often necessary to convert the coordinates from the touch display by swapping and mirroring. For the sake of simplicity, possible rotations are additionally defined.

### Contribution description

Currently the buffer size on tinydtls is set in its Makefile whenever `gcoap` module is present. This limits the ability of the user to override the value. This adds a pre-check of the `CFLAGS` to see if it was set before.

### Testing procedure

Try setting `CFLAGS += -DDTLS_MAX_BUF=<some_value>` on `examples/gcoap_dtls`, you should be able to override the default value without errors.

19539: drivers/periph_sdmmc: define a High-level SDIO/SD/MMC API and low-level SDMMC periperal driver interface r=benpicco a=gschorcht

### Contribution description

This PR provides a SDIO/SD/MMC Device API (SDMMC). It implements a SD host controller driver that provides a high-level functions using a low-level SDIO/SD/MMC peripheral driver for accessing

- MultiMediaCards (MMC) and Embedded MultiMediaCards (eMMC)
- SD Memory Cards (SD Cards) with Standard Capacity (SDSC), High Capacity (SDHC) or Extended Capacity (SDXC).

It supports:

- 1-bit, 4-bit and 8-bit data bus width
- Default Speed and High Speed
- Auto-CLK

The SDIO/SD/MMC device API (SDMMC) is divided into two parts:

1. The high-level API that implements the SD Host Controller driver and allows
   - to inititialize and identify different types of cards,
   - to access them either blockwise or bytewise,
   - to get information about the used card, and
   - to send single commands or application specific commands to the card.

2. The low-level SDIO/SD/MMC peripheral driver implements the low-level functions required by the high-level device API. It has to be implemented for each MCU.

### Limitations:

- Only one card per SDIO/SD/MMC device is supported.
- eMMCs specific features are not supported.
- UHS-I, UHS-II and UHS-III are not supported.

### Testing procedure

PR #19540, PR #19760 or PR #19786 is needed to test this PR.

19860: drivers/ft5x06: fix vendor ID for FT6xx6 and FTxxxx register addresses r=benpicco a=gschorcht

### Contribution description

This PR provides a fix of the vendor ID for FT6xx6 touch panel driver ICs and a fix of register addresses for FTxxxx.

According to the [Application Note for FT6x06 CTPM](https://cdn-shop.adafruit.com/datasheets/FT6x06_AN_public_ver0.1.3.pdf), the vendor ID of FT6x06 touch panel driver ICs is `0x11` instead of `0xcd`. Although there are no information found in the Web about the FT6x36, the FT6336U touch panel of a ESP32-S3 WT32 SC01 Plus is also working with `0x11` as vendor ID so that it seems that FT6x36 is also using `0x11` as vendor ID.

Figured out with a `stm32f723e-disco` board (revision D03). Without this PR, `tests/drivers/ft5x06` gives:
```
+------------Initializing------------+
[ft5x06] init: invalid vendor ID: '0x11' (expected: 0xcd)
[Error] Initialization failed
```
With this PR it works as expected.
```

```

Some background information found in the Web:

- According to the [STM32CubeF7](c20e6dd15b/Drivers/BSP/STM32F723E-Discovery/stm32f723e_discovery_ts.c (L24-L27)) the FRIDA LCD panel mounted on the `stm32f723e-disco` board either uses FT6x36 (prior revision D) or FT3x67 (revision D). However, the FT5x06 driver type for the card is defined as FT6x06, which does not seem correct: bb9011c3fb/boards/stm32f723e-disco/include/board.h (L59)
- According to the [STM32CubeF7](c20e6dd15b/Drivers/BSP/Components/ft6x06/ft6x06.h (L269-L270)), the vendor ID for FT6x36 should be `0xcd`. However, the FT6336U on ESP32-S3 WT32 SC01 Plus works with vendor ID `0x11`.
- The [Adafruit FT6206 library](95118cd983/Adafruit_FT6206.h (L28)) uses `0x11` as vendor id.
- The `stm32l496g-disco` board uses a FT6236 which has vendor ID `0xcd`.

So the information available on the web is confusing. Maybe, a better solution would be to accept `0x11` as well as `0xcd` as vendor ID for FT6xxx touch panels. Unfortunately, there are no documents available on the registers directly from FocalTech 😟 so it seems to be more speculation than knowledge.

19886: cpu/efm32: fix DAC configuration r=benpicco a=gschorcht

### Contribution description

The EFM32 MCU allows the reference voltage to be configured per DAC device, not per DAC channel. Also, the DAC reference voltage was defined in the configuration but not used anywhere.

At the moment we have only defined one board (`stwstk6220a`) that uses the DAC, so changing the configuration interface shouldn't be critical.

### Testing procedure

`tests/periph/dac` should still work for the `stwstk6220a`
```
BOARD=slwstk6220a make -j8 -C tests/periph/dac flash
```
I don't have a `stwstk6220a` board (EFM32 Series 0) so that I can't test it. I could only test it for the `sltb009a` board (EFM32 Series 1) with the change for VDAC in PR #19887.

b921bf460b drivers/stmpe811: init INT pin only if callback is defined
If the INT pin is initialized if the callback function parameter `cb` is `NULL`, the driver crashes the first time an interrupt is triggered. Therefore, the INT pin must be initialized only if also the callback function parameter `cb` is not `NULL`.

Even if the interrupt pin is not initialized here because the callback function parameter `cb` is NULL, the device interrupts are configured here so that they will work when the interrupt pin is initialized later, as is the case when the Touch Device API is used, for example. Since the interrupt state is cleared on each read, this is not a problem even if the interrupt pin is not used at all.

19816: drivers/lcd: code deduplication for st7735 and ili9341 r=aabadie a=gschorcht

### Contribution description

In preparation for the parallel interface support the following changes were made:

1. The code for basic communication (acquire/release SPI device, SPI transfers), which were always duplicated by copy & paste in each display driver again and again, has been moved to the LCD driver as low-level functions that are now used by the display drivers. These low level function allow 
- code deduplication and
- to define a more abstract communication interface that can then be extended later by parallel communication interface
2. Identical GPIO initializations has also been moved from display drivers to the LCD driver.
3. Using a default implementation of `lcd_set_area` function allows further code deduplication.

Finally, the `ili9341` and `st7735` drivers only implement the inialization sequence for the LCD driver IC.

### Testing procedure

`tests/drivers/ili9341` should still work for a board with an ILI9341. Tested with `esp32-wrover-kit`.
`tests/drivers/st7735` should still work for a board with a ST77xx. Tested with `esp32s3-usb-otg`.

19777: cpu/avr8_common: Prepare for rework ISR r=benpicco a=nandojve

### Contribution description

This prepares for rework how ISR is handled for AVR-8 platform. It is not expected changes on the behavior but tests on other boards were welcome to avoid regressions.

#### Improvements
 * Split UART state from ISR states. Now it is necessary two variables and GPIORx registers are automatically selected when available.
 * UART states now supports up to 8 UARTs.
 * Added AVR8_ISR macro do clean-up and hide internals related to ISR processing. This allows changes on ISR without any other changes on drivers.

### Testing procedure

Tests were conducted using atmega328p-xplained-mini and atxmega-a1u-xpro and the zigduino board was only built. The example thread_duel was used to test regressions.

### Contribution description

This PR moves the nRF52 PWM driver to `cpu/nrf5x_common` to allow nRF9160 and nRF53 to use this driver.
IP is identical on these families.

I didn't test on nRF9160DK and I didn't test if there is any regression on nRF52-based board as I don't have any so tests are welcome !
However it works fine on nRF53-based board.


### Testing procedure

Flash the `tests/periph/pwm` test application on `nrf5340dk` or `nrf9160dk`.
You can then use the `osci` command to make the onboard LEDs "breath".
You can also attach an oscilloscope and/or logic analyzer to watch the signal.

avr8_[enter/exit]_isr pair which add some boilerplate on code.
This add AVR8_ISR which clean-up the code and make it simpler
and hides any schedule detail from the user perspective.

This is a preparation for future scheduling and irq optimizations.

boards,sys/arduino: major clean up
- Rename all `arduino_pinmap.h` to `arduino_iomap.h`
    - An empty `arduino_pinmap.h` that just includes `arduino_iomap.h`
      is provided for backward compatibility
    - Move all info from `arduino_board.h` into the new file as trivial
      macros, so that they can also be used outside of sketches
    - The new name reflects the fact not just pin mappings, but also
      other I/O features such as PWMs are mapped
- Drop all `arduino_board.h`
    - `arduino_board.h` and `arduino_iomap.h` now provide the exact
      same information, just in a different format
    - a generic `arduino_board.h` is provided instead that just
      uses the info in `arduinio_iomap.h` and provides them in the
      format the code in `sys/arduino` expects it
- Add fine grained features to indicate for mappings
    - availability of mappings for analog pins, DAC pins, PWM pins,
      UART devices, SPI/I2C buses to the corresponding RIOT
      identification can now be expressed:
        - `arduino_pins`: `ARDUINO_PIN_0` etc. are available
        - `arduino_analog`: `ARDUINO_A0` etc. are available
        - `arduino_pwm`: `ARDUINO_PIN_13_PWM_DEV` etc. are available
        - `arduino_dac`: `ARDUINO_DAC0` etc. are available
        - `arduino_uart`: `ARDUINO_UART_D0D1` or similar are available
        - `arduino_spi`: `ARDUINO_SPI_ISP` or similar are available
        - `arduino_i2c`: `ARDUINO_I2C_UNO` or similar are available
    - mechanical/electrical compatibility with specific form factors
      can now be expressed as features:
        - `aruino_shield_nano`: Arduino NANO compatible headers
        - `aruino_shield_uno`: Arduino UNO compatible headers
        - `aruino_shield_mega`: Arduino MEGA compatible headers
        - `aruino_shield_isp`: ISP header is available

This provides the groundwork to implement shield support as modules
that can rely on the I/O mappings, rather than having to provide a
configuration per board.

19718: drivers/dht: busy wait reimplementation r=benpicco a=hugueslarrive

### Contribution description

In PR #19674, I also provided quick and dirty fixes to restore functionality on esp8266 and enable operation on AVR. While reviewing PR #18591, it became apparent to me that this driver needed a refresh, particularly its migration to ztimer.

The cause of the malfunction on esp8266 was that since the default switch to ztimer as the backend for xtimer, XTIMER_BACKOFF was no longer taken into account. Therefore, the correction I provided in PR #19674 simply made explicit what was previously done implicitly with xtimer and now needs to be done explicitly with ztimer (spinning instead of sleeping).

Moreover, it was unnecessarily complex to measure the pulse duration in a busy-wait implementation, which required 2 calls to ztimer_now() and  32-bit operations expensive on 8-bit architecture. Instead, it is sufficient to read the state of the bus at the threshold moment.

Finally, in practice, it is possible to reduce the read interval (down to less than 0.5s for DHT22) by "harassing" the DHT with start signals until it responds.

This re-implementation brings the following improvements:
- Many backports from `@maribu's` IRQ based implementation (#18591):
  - Use of ztimer
  - Use of errno.h
  - Use of a dht_data structure to pass arguments, to facilitate integration
  - Adaptation of the bit parsing technique to parse bits into the data array
- Reintroduction of DHT11/DHT22 differentiation.
- Separation of `dht_read()` steps into functions for better readability and the ability to share certain functions among different implementations
- Sensor presence check in `dht_init()`
- ~~Automatic adjustment to a minimum data hold time~~
- Default input mode changed to open drain (a pull-up resistor should be placed close to the output if necessary but not close to the input)
- AVR support without platform-specific handling by avoiding  ztimer_spin() and using the overflow of an 8-bit variable as a pre-timeout to minimize time-consuming ztimer_now() calls

Regarding the changes in the start signal sequence and the removal of the `_reset()` function:
![nano_dht_read_2](https://github.com/RIOT-OS/RIOT/assets/67432403/95966813-2b5f-4a0f-a388-8ac630526ab2)

~~In the previous implementation, there was an unnecessary spike at the beginning of the signal sequence, corresponding to START_HIGH_TIME. This spike has been removed in the re-implementation, as it is unnecessary. Instead, the MCU now simply pulls the signal low for START_LOW_TIME and then releases the bus, which is sufficient for initiating communication with the DHT sensor.~~ Actually, it is necessary to raise the bus level; otherwise, the _wait_for_level() called immediately after to check the response of the DHT may read the port before the signal level is raised, resulting in a false positive.

Additionally, the previous implementation had an issue where the MCU switched back to output mode and went high immediately after reading the 40 bits of data. However, the DHT sensor was still transmitting 2 or 3 additional bytes of '0' at that point, causing a conflict. This issue has been resolved in the re-implementation:

~~Regarding the optimization for AVR, I have performed measurements of `_wait_for_level()` until timeout (85 loops):~~
~~- on esp8266-esp-12x: 264 µs, which is 3.11 µs per loop~~
~~- on nucleo-f303k8: 319 µs, which is 3.75 µs per loop~~
~~- on arduino-nano: 3608 µs, which is 42.45 µs per loop~~
~~Duration measurements on the Arduino Nano:~~

19746: buildsystem: Always expose CPU_RAM_BASE & SIZE flags r=benpicco a=Teufelchen1

### Contribution description

Hello 🐧 

This moves the definition of `CPU_RAM_BASE/SIZE` from being only available in certain situation to be always available.
Reason for change is to simplify common code in the cpu folder.

In cooperation with `@benpicco` 

### Testing procedure

Passing CI


### Issues/PRs references

First usage will be in the PMP driver. Although there is more code in RIOT that could be refactored to use these defines instead of hacks / hardcoded values.

19735: nrf5x_common: Clear I2C periph shorts r=benpicco a=bergzand

### Contribution description

The I2C peripheral's shortcuts are used with the read and write register to automatically stop the I2C transaction or to continue with the next stage.

With simple I2C read and write bytes these shorts are not used, but are also not cleared by the function in all cases, causing it to use the shortcut configuration set by a previous function call. This patch ensures that the shorts are always set by the read and write functions

### Testing procedure

Should be possible to spot with a logic analyzer and the I2C periph test. Maybe the HIL test can also detect it :)
