Imre Deak 0f5a9be157 drm/i915: take a power domain reference while checking the HDMI live status 
There are platforms that don't need the full GMBUS power domain (BXT)
while others do (PCH, VLV/CHV). For optimizing this we would need to add
a new power domain, but it's not clear how much we would benefit given
the short time we hold the reference. So for now let's keep things
simple.

This fixes a regression introduced in
commit 237ed86c69
