A receiver endpoint must bind a notification to any sender endpoint before the latter can signal the notification to the former. The receiver assigns one or more doorbells to a specific sender. Only the sender can ring these doorbells. A receiver uses the FFA_NOTIFICATION_BIND interface to bind one or more notifications to the sender. A receiver un-binds a notification from a sender endpoint to stop the notification from being signaled. It uses the FFA_NOTIFICATION_UNBIND interface to do this. Allow the FF-A driver to be able to bind and unbind a given notification ID to a specific partition ID. This will be used to register and unregister notification callbacks from the FF-A client drivers.
