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.
