drm/i915: Add functions to get a power well's state/name/domains/mask/refcount

Add functions to get a power well's actual- and cached-enabled state,
name, domain mask and refcount, as a step towards making the low-level
power well internals (i915_power_well_ops/desc structs) hidden.

No functional change.
