Adds the board definitions for the nucleo_h563zi board.
Notes:
DAC: enable output on pa5, which is available on the ST Zio and morpho
connectors.
UM3115 in table 21 wrongly lists pa15 on the positions where pa5 is.
The only other option for the dac output is pa4 which is reserved for
for VBUS_SENSE.
