Matt Roper 171596bfc3 drm/i915/xe3lpd: Add new display power wells
Xe3's power well handling is similar to previous platforms, but there
are a few changes that need to be handled to ensure optimal power
management:
 - PGB now only depends on PG1, not PG2
 - Transcoder B is now in PG1 (was previously in PGB)
 - Transcoders C & D are now in PG2 (were previously in PGC/PGD)
 - DC states now require PG2 to be off (whereas on Xe2 it could remain
   on as a dependency of PGB, although the features inside of it could
   not be used).
