Daniel Vetter pointed out that locking in the GuC submission code was
overly complicated, let's clean this up a bit before introducing more
features in the GuC submission backend.
Also fix some CI failures, port fixes from our internal tree, and add a
few more selftests for coverage.
Lastly, add some kernel DOC explaining how the GuC submission backend
works.
v2: Fix logic error in 'Workaround reset G2H is received after schedule
done G2H', don't propagate errors to dependent fences in execlists
submissiom, resolve checkpatch issues, resend to correct lists
