[PATCH 0/4] Add test for G2G communications

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

Platforms with multiple GuCs (multi-GT and/or multi-tile) have a
mechanism for sending messages from one GuC to another. This relies on
the KMD configuring buffers correctly and informing the GuCs about
them. Support for that was merged a while back. So add a test to go
with it.

Also, improve the firmware CSS header structure and defines to better
match the spec and to add missing fields that are useful.
