From: Ville Syrjälä <[email protected]> Rename vlv_primary_min_alignment() to vlv_plane_min_alignment() and use it to replace vlv_sprite_min_alignment() since the behaviour is now identical when the plane init doesn't set up any async flips stuff.
Technically VLV/CHV sprites do support async flips, so this also makes us a bit more future proof if/when we extend async flip support to more than one plane.
