Let's do it the other way around, so that you can actually tell when the power well would get enabled. This will also allow us to add new power domains without accidentally adding it to the HSW/BDW display power domains. The current set of domains looks rather buggy even: - POWER_DOMAIN_MODESET is included in the display power well needlessly - DDI-B to DDI-E were not part of the display power well when they should be So let's fix that up while at it.
