firmware: arm_ffa: Add interface to send a notification to a given partition
The framework provides an interface to the sender endpoint to specify
the notification to signal to the receiver endpoint. A sender signals
a notification by requesting its partition manager to set the
corresponding bit in the notifications bitmap of the receiver.
Expose the ability to send a notification to another partition.
