arm-bsp/trusted-firmware-m: corstone1000: Permit FWU calls in RSE-COMMS

Browse Source 
Add support to permit FWU calls in RSE-COMMS Trusted-Firmware-M for Corstone-1000
This change is required to allow the transmission of PSA FWU related
calls between Cortex A and Cortex M side on Corstone-1000.
For every PSA call from A side, the RSE-COMMS at M side validates, if the
call is allowed or not.
