drm/i915: Define VLV/CHV display power well domains properly

Currently we're using POWER_DOMAIN_MASK as the power domains for the
display power well on VLV/CHV. That includes all power domains even
though the disp2d/pipe-a power well is not needed for a lot of things.
Let's reduce these to what we actually need.
