drm/i915: Add function to call a power well's sync_hw() hook

Add a function to call a power well's sync_hw() hook, instead of
open-coding the same, as a step towards making the low-level
power well internals (i915_power_well_ops/desc structs) hidden.

The cached-enable state should be always up-to-date, so update it
whenever sync_hw() is called.

No functional change.
