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.
