We want to program slave planes with the master plane_state for
properties such as FB, rotation, coordinates, etc, but the
slave plane_state for all programming parameters.
Instead of special casing NV12 Y-planes, we make the code more
generic, Y planes are programmed with separate state from the UV
plane.
This will allow us to program planes on a bigjoiner slave crtc in
a similar way.
This also requires the VMA to be copied to the slave, which is
done in prepare_plane_fb().
