drm/i915/display: add subplatform group for HSW/BDW ULT

Browse source

Add support for defining aliases for subplatform groups, such as HSW/BDW
ULT that covers both ULT and ULX.

ULT is a special case, because we slightly abuse the ULT subplatform
both as a subplatform and group, but with the way this is defined, it
should be fairly clear.

This follows i915 core and IS_HASWELL_ULT()/IS_BROADWELL_ULT()
conventions, i.e. "is ULT" also matches ULX platforms.

Note: Pedantically, this should have been done earlier, but it's only
feasible now that we no longer have a subplatform enum and can actually
initialize multiple subplatforms.

v2: Use the subplatform group idea
