[Intel-gfx] [PATCH 12/16] drm/i915/bxt: Sanitize the DBUF HW state together with CDCLK

When determining whether CDCLK is enabled by BIOS and so we should skip reprogramming it, we didn't check the related DBUF power request and state. In theory BIOS could enable one without the other so check for this case and reprogram things if something is amiss. Signed-off-by: Imre Deak
