drm/i915: Store frontbuffer_bits in the plane
Avoid some 'switch (plane->type)' by storing the fronbuffer_bits in intel_plane. Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> [danvet: use singular frontbuffer_bits in intel_plane since a plan can only ever have one bit. Discussed with Ville on irc.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
