[PATCH 0/3] GuC based reset engine

We've been supporting reset-engine in execlist submission mode for a
while, but with GuC the resubmission path had to be different because we
used to re-enable the engines before GuC.

Thanks to Michal Winiarski GuC preemption changes, the firmware is
enabled before restarting the engines, so the replay part after
resetting an engine is no longer different.

The only change now is that the reset-engine is requested to the
firmware via a H2G command, and GuC is the one in charge of acquiring the
forcewake and idling the engine before reseting it.

(The first patch is a cosmetic change, which I'm sure Tvrtko doesn't
remember he reviewed [1]).
