drm/i915: add intel_display_power_enabled
This should replace intel_using_power_well. The idea is that we're
adding the requested power domain as an argument, so this might enable
the code to look less platform-specific and also allows us to easily
add new domains in case we need.
v2: Add more domains to enum intel_display_power_domain
v3: Even more domains requested
