firmware: arm_ffa: Tear down driver during shutdown
The platform core invokes a driver's shutdown callback, rather than its
remove callback, while preparing devices for a normal kexec. Without a
shutdown callback, the FF-A driver leaves notifications, partition devices,
and the RX/TX mapping active before the replacement kernel is booted.
Use ffa_remove() for shutdown so the existing cleanup runs before a normal
kexec and other orderly system shutdowns.
