drm/i915/pc8: Add parent interface for PC8 forcewake tricks
We use forcewake to prevent the SoC from actually entering
PC8 while performing the PC8 disable sequence. Hide that
behind a new parent interface to eliminate the naked
forcewake/uncore usage from the display power code.
v2: Mark the interface optional and warn if
someone calls it when not provided (Jani)
Include the header to make sure the extern
declaration matches the definition (Jani)
v3: Rebase due to shuffling
