drm/i915/display: Make POWER_DOMAIN_*() always result in enum intel_display_power_domain
In the hope of contributing to type safety in our code, let's ensure
that the type returned by the POWER_DOMAIN_*() macros is always of type
enum intel_display_power_domain.
v2:
- Remove accidental +1 in definition of POWER_DOMAIN_PIPE(). (Jani)
