[RFC] android/client: Add AVRCP register_notification_rsp support

[Ravi kumar Veeramally <ravikumar.veeramally@xxxxxxxxxxxxxxx>]

Input for this call doesn't require all parameters of structure
to be filled at the same time. Input data depepnds on event_id
and type. Implemented this api support based on
android/hal_avrcp.c:register_notification_rsp.
