From: Ville Syrjälä <ville.syrj...@linux.intel.com>
As only a subset of primary planes are FBC capable there's no need
to waste fences on all of them. So let's skip the fence if the plane
isn't even fbc capable.
In the future we might extend this to skip the fence even for FBC
capable planes if the crtc and/or plane state isn't suitable
for FBC.
