[PATCH 1/5] lib: utils: Add RPMI REQUEST_FORWARD service group defines

[marouene.boubakri at oss.nxp.com]

From: Marouene Boubakri <marouene.boubakri at nxp.com>

Add the service group ID, service IDs, notification event ID and the
request and response data layouts of the RPMI REQUEST_FORWARD service
group (SERVICEGROUP_ID 0x000D) defined by RPMI v1.0.

The forwarded request message carried by REQFWD_RETRIEVE_CURRENT_MESSAGE
is a complete RPMI message including its 8-byte message header, unlike
the message data exchanged over an SBI MPXY channel.
