drm/i915: Convert remaining users of 32bit power domain masks

drm/i915: Convert remaining users of 32bit power domain masks

I screwed up the rebase of commit f5776445bafe ("drm/i915: Make power
domain masks 64 bit long") before sending v2, causing a couple of
conversions from 32 to 64 bit masks to be lost.

Fixes: f5776445bafe ("drm/i915: Make power domain masks 64 bit long")
