boards: arm: st: nucleo_h7s3l8: Add fdcan1 



Enable support for FDCAN1 on nucleo_h7s3l8 board. PD0 (RX) and PD1 (TX)
are used for interfacing an external CAN transceiver according to the
breakout connector description in the board's schematic.

FDCAN

=====



The Nucleo H7S3L8 board does not have any onboard CAN transceiver. In order to

use the FDCAN bus on this board, an external CAN bus transceiver must be

connected to pins PD0 (RX) and PD1 (TX).
