Enable support for ARM FFA interface on Renesas R-Car X5H R8A78000 .
The Firmware Framework for Arm A-profile processors describes interfaces
(ABIs) that standardize communication between the Secure World and Normal
World leveraging TrustZone technology. The FFA is used for example for
communication with Hafnium or virtualized OPTEE-OS.
