drm/i915: vlv: factor out vlv_force_gfx_clock and check for pending force-off
This will be needed by the VLV runtime PM helpers too, so factor it out. Also add a safety check for the case where the previous force-off is still pending, since I'm not sure if Punit can handle a new setting while the previous one hasn't settled yet. v2: - unchanged v3: - add a note to the commit message about the safety check (Ville) Signed-off-by:Imre Deak <imre.deak@intel.com> Reviewed-by:
