add CAN support to Nucleo L432KC (Nucleo 32) #20837
Description
Description
The Nucleo L432KC board is a Nucleo 32 board supported by RIOT OS.
This board supports CAN interface. However, CAN periph is not enabled into Makefile.features and the definition of the CAN pins is not correct for the STM32L432KC : PA11/PA12 instead of PB8/PB9 into cpu/stm32/include/can_params.h
Steps to reproduce the issue
The following patch is enough for using the CAN bus with Nucleo L432KC
