[PATCH 2/2] include: mailbox: Update RPMI notification structs and add Performance event definitions

[David E. Garcia Porras]

Add RPMI notification header size and offset macros, and event header
composition macro. Add rpmi_event_notification_state enum with disable,
enable, and return current state IDs. Add req_state field to
rpmi_enable_notification_req and current_state field to
rpmi_enable_notification_resp for RPMI spec compliance.

Add notification event ID enum and data structures for RPMI Performance
service group events: power change, limit change, and level change.
