drm/i915/guc: Prepare to handle messages from CT RECV buffer
GuC can respond to our commands not only by updating SEND buffer
descriptor, but can also send a response message over RECV buffer.
Guc can also send unsolicited request messages over RECV buffer.
Let's start reading those messages and make placeholders
for actual response/request handlers.
v2: misc improvements (Michal)
v3: change response detection (Michal)
invalid status is protocol error (Michal)
v4: rebase
v5: fix checkpatch (Michel)
don't use fields before check (Jani)
add some documentation (Michal)
