This is an ugly hack imo. Better to add the scaler pointer to the plane
state, set it in compute_config once we're done and not pass it around
like this. Or we also pass around a pointer to the right crtc_state.
Also, if we pass around plane_state I think all the crtc_x/y/w/h and x/y
and src_x/y/w/h should disappear, for a really clean vfunc interface.
