drm/i915/bdw: add BDW DDI buf translations for eDP
Broadwell has different DDI buffer translations for eDP and DP, so add support for the missing eDP and keep Haswell the same. A future patch addresses the suggestion from Art to check for eDP on port D and use the eDP values there, too. v2: Make checkpatch happy.
