Doxygen fails to render inline code in headers correctly in the
version the CI uses. So, work around the issue by not typestetting
`stm32flash` as inline code but as regular text.

19574: cpu/stm32/periph_gpio: reset PU/PD for ADC channels r=maribu a=gschorcht
### 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.

19577: cpu/esp32: fix remaining compilation errors for GCC 12.2 r=maribu a=gschorcht
### Contribution description
This PR fixes one problem of CI compilation.
With [PR #227](https://github.com/RIOT-OS/riotdocker/pull/227) `riotdocker` was updated to GCC 12.2 . Obviously, following parts were not covered by compilation test before:
- [ ] `esp_eth`
- [ ] `esp_hw_counter`
- [ ] `esp_can`

This fixes the following compilation issues:

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

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`

19575: treewide: fix format specifiers r=maribu a=maribu
### Contribution description
This brings format specifiers and the passed type back into sync. This won't change observable behavior in one case, and won't even change machine code in the other. But formally, this fixes bugs.

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.
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 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.
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 or to use the DAC channel also for other on-chip peripherals.

GCC 12 gives out of bounds warnings when the resulting address is out
of bounds of what GCC assumes to be the valid address space. It seems
that by default the address 0x0 is not considered valid (which would
be a NULL pointer and typically not mapped in a userspace behind an MMU
scenario), but in fact is valid on bare metal hardware. At least on
AVR and MSP430 this needs to be set. On many Cortex M MCUs 0x0 is also
a valid address (e.g. often the flash is mapped there), but seemingly
for them `--param=min-pagesize=0` is already the default. In any case,
it won't hurt to set it explicit for them as well.
An `INSERT AFTER` directive no longer can refer to a different linker
script included with `-T path/to/script.ld`. Instead, this adds wrapper
linker scripts that just `INCLUDE` the three individual linker scripts.
This way, the xfa.ld can safely refer back to sections defined in
the vendor linker script.
For some reason, this approach cause the exact issue it fixes for
binutils 2.40 with the binutils in the CI. We stick with the old
linker flags with binutils prior 2.40 to be compatible with both
conflicting behaviors.
The best approach would be to come up with something that works across
different versions of binutils; but no such solution materialized.
