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
