drm/i915/guc: Update GuC power domain states

Browse source

We should update GuC power domain states also when GuC submission
is disabled, otherwise GuC might complain or ignore our requests.
This seems to be required for all currently released GuC firmwares.

v2: it is only needed by pre-Gen11 firmwares
