drm/i915/gt: Use hw_engine_masks as reset_domains

Browse Source 
We need a way to reset engines by their reset domains.
This change sets up way to fetch reset domains of each
engine globally.

Changes since V1:
	- Use static reset domain array - Ville and Tvrtko
	- Use BUG_ON at appropriate place - Tvrtko
