From: Ville Syrjälä <ville.syrj...@linux.intel.com>
Split up intel_check_primary_plane() and intel_check_sprite_plane()
into per-platform variants. This way we can get a unified behaviour
between the SKL universal planes, and we stop checking for non-SKL
specific scaling limits for the "sprite" planes. And we now get
a natural place where to add more plarform specific checks.
v2: Split the .check_plane() calling convention change out (José)
