Add an ID for the HSW/BDW global display power well for consistency. The
ID is selected so that it can be used to get at the HW request and
status flags with the corresponding GEN9+ macros. Unifying the HSW/BDW
and GEN9+ versions of these macros and the power well ops using them
will be done in follow-up patches.
v2:
- Rebased on v2 of patch 2.
