drm/i915: Convert the u64 power well domains mask to a bitmap

To remove the aliasing of the power domain enum values in a follow-up
patch in this patchset (requiring a bigger mask) and allow for defining
additional power domains in the future (at least some upcoming TypeC
changes requires this) convert the u64 i915_power_well_desc::domains
mask to a bitmap.

For simplicity I changed the for_each_power_domain_well() macros to
accept one domain only instead of a mask, as there isn't any current
user passing multiple domains.

v2: Don't add a typedef for the bitmap struct. (Jani)
