Make it possible to adjust the rc_model_size parameter instead of hardcoding it all over the place. Only actually change the size for i915 DSI DSC.
Patch 3 for AMD isn't really required, but it felt like a natural cleanup to incorporate.
Vandita, please check if this helps with the DSI DSC woes.
BR, Jani.
