Contribution description

This PR adds ADC configuration to the nucleo-l432kc board.

Testing procedure

Flash the board using tests/periph/adc program. Check if measured values changes when A0-A5 pins are
connected to the 3,3V, GND or to the potentiometer.

You should see output similar to that (A0 connected to GND).

main(): This is RIOT! (Version: 2024.04-devel-2895-gc6badb-nucleo-l432-ADC)

RIOT ADC peripheral driver test

This test will sample all available ADC lines once every 100ms with
6 to 16-bit resolution and print the sampled results to STDOUT.
Not all MCUs support all resolutions, unsupported resolutions
are printed as -1.

Why are A4 and A5 not defined? Pin collision?

Why are A4 and A5 not defined? Pin collision?

In default board configuration they are not connected - for more details see table 8 from board manual.
