- ProtocolGuid - Protocol to register notification event on.

-
- NotifyFunction - EFI notification routine.
-
- NotifyContext - Context passed into Event when it is created.

- Registration - Registration key returned from RegisterProtocolNotify().
-
-Returns:
-
- The EFI_EVENT that has been registered to be signaled when a ProtocolGuid
- is added to the system.
