[Intel-gfx] [PATCH 07/18] drm/i915: Store ggtt_view in plane_state

[Ville Syrjala]

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

Stash the gtt_view structure into the plane state. This will become
useful when we do GTT remapping as the gtt_view will not come directly
from the fb anymore.
