drm/i915/skl: Implement drm_plane vfuncs
SKL Uses the same hardware for all planes now, so called "universal" planes. Ie both the primary planes and sprite planes share the same logic. This patch implements the drm_plane vfuncs for "sprites" ie planes that aren't the primary plane. v2: Couple of fixes: - Actually enabled the planes and fix the plane number Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
