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

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.
