[Intel-gfx] [PATCH 5/5] drm/i915: Use the vblank power domain disallow or disable DC states.

Disable DC states before enabling vblank interrupts and conversely enable DC states after disabling. Since the frame counter may have got reset between disabling and enabling, use drm_crtc_vblank_restore() to compute the missed vblanks. Cc: Daniel Vetter Cc: Ville Syrjälä Cc: Rodrigo Vivi Signe
