Arm FF-A driver fixes for v5.15

Couple of fixes addressing issues when FFA driver is build as a module.
One adds the device unregistration which was missing and causes issue
when loading the module second time after unloading once. Another one
adds the missing remove callback on the ffa bus which was missing due
to which modules depending on FFA(e.g. OPTEE) will fail to remove the
device and faults next time that module is loaded again.
