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
