As discussed in [1] we are breaking that large series into a several
smaller ones. This series is the non-interface changing part of step #2
- it makes all the changes needed before updating the GuC firwmare to a
new version without breaking any old interfaces.

A follow on series will be squashed into a single patch that updates the
GuC firmware + the required interface changes.

Patch number #13 needs an Ack from Michal Wajdeczko.
Patch number #6, #15 need reviews.

v2: Fix some checkpatch warnings, add patch number #6 to address CI
failure [2] in first rev

Yep, other series submitted around the same time as this had the same warnings.

AFAICT, none of these warnings are related to this patch set.
