19618: cpu/stm32: fix riotboot settings for L4 and WB r=benpicco a=gschorcht

### Contribution description

This PR fixes the `riotboot` configuration for L4 and WB.

The family is not called `stm32l4` or `stm32wb` but `l4` and `wb`. That is, the `riotboot` configuration didn't work at all. Furthermore, a minimum `RIOTBOOT_LEN` of `0x2000` is required for L4.

Found when investigating the compilation errors for `bootloaders/riotboot_serial` in PR #19576.

### Testing procedure

1. Green CI.
2. Use the following commands:
    ```
    BOARD=nucleo-l496zg make -C tests/riotboot info-debug-variable-RIOTBOOT_HDR_LEN
    BOARD=p-nucleo-wb55 make -C tests/riotboot info-debug-variable-RIOTBOOT_HDR_LEN
    ```
    In master these commands give
    ```
    0x400
    ```
    With this PR these commands give
    ```
    0x200
    ```
    as expected.
3. Use the following commands:
    ```
    BOARD=nucleo-l496zg make -C tests/riotboot info-debug-variable-RIOTBOOT_LEN
    BOARD=p-nucleo-wb55 make -C tests/riotboot info-debug-variable-RIOTBOOT_LEN
    ```
    In master these commands give
    ```
    0x1000
    ```
    With this PR these commands give
    ```
    0x2000
    ```
    as expected.

19581: cpu/samd5x: enable FDPLL1 at 200MHz r=benpicco a=dylad

### Contribution description

This PR allows to use the second FDPLL (the first one is used to generated the 120MHz frequency used by the core and some peripherals). The second FDPLL is setup to run at 200MHz which is the maximum allowed by this MCU.
In fact, I reused the existing function which setup FDPLL0 so it can be used in a generic way for both PLL (since they are the same IP).

I change the way the computation offset (left shift by 5)  is done because 200MHz << 5 wouldn't fit inside an `uint32_t` and I wanted to avoid using an `uint64_t` here

Two additional commits are present for a small cleanup and a fix.

This is currently unused in our codebase, so it shouldn't impact this platform too much as the `ONDEMAND` bit is set. the FDPLL will not be running out of the box. But `@gschorcht` might need it pretty soon.

### Testing procedure

This PR can be tested on a `same54-xpro` and an oscilloscope using the following the patch:

19433: cpu/esp32: deduplication in Kconfig for ESP32x SoCs r=aabadie a=gschorcht

### Contribution description

This PR reduces the code duplication in Kconfig for ESP32x SoCs.

It defines a new common CPU symbol `CPU_COMMON_ESP32X` in Kconfig that is used by all `CPU_FAM_ESP32x` symbols. It selects all features, modules and packages that are common for all ESP32x SoC variants. This avoids the selection of features, modules and packages again and again for each ESP32x SoC variant.

The same is done in PR #19432 for common ESP32x board definitions.

19619: cpu/arm7: Fix undefined behavior based on invalid assembly r=aabadie a=Teufelchen1

### Contribution description

Hellooo! 🦤

In this PR a single `NOP` is added after an `ldm` in ARM7 common code in the scheduling management.
The change is necessary because this particular `ldm` affects certain banked registers, including `R14 / lr`. The next instruction then immediately accesses `lr`. This is invalid and the exact effect depends on the underlying hardware implementation. An intermediate `NOP` ensures correct behaviour in such cases.

The ARM docs can be found [here](https://documentation-service.arm.com/static/5f8dacc8f86e16515cdb865a), in section `A4.1.21 LDM (2)`. It states:
> In ARM architecture versions earlier than ARMv6, this form of LDM must not be
followed by an instruction that accesses banked registers. A following NOP is a good
way to ensure this.


### Testing procedure

Without this change, on the Game Boy Advance, RIOT behaves irregularly. With the `NOP`, it works fine!
If possible, this change should be tested on other ARM7 hardware as well but I do not have access to any.  

----

Special thanks `@pyropeter` for spotting the extremely tiny note on this issue within the ARM docs. You saved me hours of tears! 👾

19572: cpu/stm32/periph_pwm: support of complementary timer outputs r=maribu a=gschorcht

### Contribution description

This PR provides the support of complementary timer outputs as PWM channels for advanced timers (TIM1/TIM8).

To use a complementary output of an advanced timer as PWM channel, the output is defined with an offset of 4, i.e. normal outputs are in the range of 0 to 3 (CH1...CH4) and complementary outputs are in the range of 4 to 6 (CH1N...CH3N). If the defined output is less than 4, the normal output is enabled, otherwise the complementary output is enabled.

This change is required to support PWM on boards that have connected the complementary outputs of advanced timers to the PWM connector pins, for example the STM32L496-DISCO board.

### Testing procedure

- Green CI
- Use any STM32 board which supports the `periph_pwm` feature. `tests/periph_pwm` should still work.
- Change the configuration for this board so that either timer TIM1 or TIM8 and a complementary channel is used for any exposed GPIO. `tests/periph_pwm` should also work with such a configuration.

19571: cpu/stm32/periph_adc: fixes and improvements for L4 support r=benpicco a=gschorcht

### Contribution description

This PR provides the following fixes and improvements for the `periph_adc` implementation for STM32L4.
- Support STM32L496AG added.
- Instead of defining the number of ADC devices for each MCU model, the number of ADC devices is determined from ADCx definitions in CMSIS header.
- MCU specific register/value defines are valid for all L4 MCUs, model based conditional compilation is removed.
- The ADC clock disable function is fixed using a counter. The counter is incremented in `prep` and decremented in `done`. The ADC clock is disabled if the counter becomes 0.
- For boards that have not connected the V_REF+ pin to an external reference voltage, the VREFBUF peripheral can be used as V_REF+ (if supported) by setting `VREFBUF_ENABLE=1`.
- The ASCR register is available and has to be set for all STM32L471xx, STM32L475xx, STM32L476xx, STM32L485xx and STM32L486xx MCUs. Instead of using the CPU model for conditional compilation, the CPU line is used to support all MCU of that lines.
- Setting of SQR1 is fixed. Setting the SQR1 did only work before because the `ADC_SRQ_L` is set to 0 for a sequence length of 1.
- Setting the `ADC_CCR_CKMODE` did only work for the reset state. It is now cleared before it is set. Instead of using the `ADC_CCR_CKMODE_x` bits to set the mode, the mode defines are used.
 - Support for V_REFINT as ADC channel added.

19573: cpu/stm32/periph_dac: small improvements r=maribu a=gschorcht

### Contribution description

This PR provides the following improvements for `periph_dac` on STM32

- Support for `RCC_APB1ENR1_DAC1EN` symbol added.
- For boards that have not connected the V_REF+ pin to an external reference voltage, the VREFBUF peripheral can be used as V_REF+ (if supported) by setting `VREFBUF_ENABLE=1`.
- If the DAC peripheral has a mode register (`DAC_MCR`), it is set to normal mode with buffer enabled and connected to external pin and on-chip peripherals. This allows to measure the current value of a DAC channel with an ADC channel or to use the DAC channel also for other on-chip peripherals.

### Testing procedure

- Green CI
- `tests/periph_dac` should still work for any board supporting the `periph_dac` feature.

### Contribution description

This PR provides a small fix that is relevant when a GPIO has been used as input/output with a pull resistor before it is initialized as an ADC channel.

The PU/PD configuration has to be `0b00` for analog outputs which is corresponds to the reset state. However, if the GPIO is not in the reset state but was used digital input/output with any pull resistor, the PU/PD configuration has also to be reset to use it as ADC channel.

### Testing procedure

- Green CI
- The `periph_adc` test application should still work for any board that supports the `periph_adc` feature.

19484: makefiles/arch/msp430.inc.mk: Fix compilation issues with GCC 12 r=maribu a=maribu

### Contribution description

This fixes the following compilation issues:

    /home/maribu/Repos/software/RIOT/cpu/msp430fxyz/periph/gpio.c: In function 'gpio_periph_mode':
    /home/maribu/Repos/software/RIOT/cpu/msp430fxyz/periph/gpio.c:95:15: error: array subscript 0 is outside array bounds of 'msp_port_isr_t[0]' [-Werror=array-bounds]
       95 |         sel = &(isrport->SEL);
          |               ^~~~~~~~~~~~~~~
    cc1: all warnings being treated as errors

by adding `CFLAGS += --param-min-pagesize=0` for GCC 12 (same issue as already fixed for AVR).

and:

    /usr/lib/gcc/msp430-elf/12.2.0/../../../../msp430-elf/bin/ld: warning: /home/maribu/Repos/software/RIOT/cpu/msp430_common/ldscripts/xfa.ld contains output sections; did you forget -T?

by adding the missing `-T`.

### Testing procedure

The following should still work:

- `make BOARD=msb-430 -C examples/hello-world`
- `make BOARD=msb-430 -C tests/xfa flash test`

### Issues/PRs references

af8a87ad99 cpu/stm32/periph_adc: fix SQR1 setting for L4
The setting of SQR1 is fixed. Setting the SQR1 did only work before because the ADC_SRQ_L is set to 0 for a sequence length of 1.

5483235c61 cpu/stm32/periph_adc: use L4 lines instead of L4 models
The ASCR register is available and has to be set for all STM32L471xx, STM32L475xx, STM32L476xx, STM32L485xx and STM32L486xx MCUs. Instead of using the CPU model for conditional compilation, the CPU line is used to support all MCU of that lines.

ccba70ff61 cpu/stm32/periph_adc: support for internal V_REF+
For boards that have not connected the V_REF+ pin to an external reference voltage, the VREFBUF peripheral can be used as V_REF+ if supported by setting `VREFBUF_ENABLE=1`.

d8bd2d9f43 cpu/stm32/periph_adc: fix ADC clock disable for L4
The ADC clock disable is fixed using a counter. The counter is incremented in `prep` and decremented in `done`. The ADC clock is disabled if the counter becomes 0.
