drm/i915/cfl: Basic DDI plumbing for Coffee Lake.
All here is pretty much like Kabylake.
Including CFL-U has to use same ddi translation table
as KBL-U for now.
v2: Include missed IS_COFFEELAKE on edp trans table. (DK)
Handle CFL-U with same translation table as KBL-U. (DK and
confirmed with HW engineers)
v3: Adding missed case for IS_CFL_ULT. (DK).
v4: Duh! Now with the real IS_CFL_ULT instead of KBL one. (DK)
Also use IS_GEN9_BC when possible. (DK)
