Arm FF-A fixes for v6.16
Couple of fixes to address:
1. The safety and memory issues in the FF-A notification callback handler:
The fixes replaces a mutex with an rwlock to prevent sleeping in atomic
context, resolving kernel warnings. Memory allocation is moved outside
the lock to support this transition safely. Additionally, a memory leak
in the notifier unregistration path is fixed by properly freeing the
callback node.
2. The missing entry in struct ffa_indirect_msg_hdr:
The fix adds the missing 32 bit reserved entry in the structure as
required by the FF-A specification.
