drm/i915: Add PLL .compare_hw_state() vfunc
Chunk up the humongous dpll_hw_state comparison check into per-platform
variants, implemented in the dpll_mgr. This is step one in allowing
each platform (or perhaps even PLL) type to have a custom hw state
structure instead of having to smash it all into one.
