[Intel-gfx] [PATCH 00/12] Preemption with GuC, second try

[Michał Winiarski]

I've included most of the review feedback, some of which caused additional
patches to appear. We're now using a separate object for GuC shared data (while
I was there I also added cleanup to guc stage desc pool creation). Since I
needed to iterate over clients in one additional place, I've converted them to
an array.
We're now also flushing the worker on reset and no longer using ordered wq
(using the one with max_active equal to number of engines).
