[PATCH 2/4] drm/i915: Handle intel_plane and intel_plane_state in to_intel_display()

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

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

Allow one to pass intel_plane/intel_plane_state to
to_intel_display(). Works exactly like their crtc
counterparts.
