[Intel-gfx] [PATCH] drm/i915: Remove the old global state stuff

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

With the dbuf code mostly converted over to the new global state
handling we can remove the leftovers of the old global state
stuff.
