Currently we are enabling selective fetch for all planes that are visible. This is suboptimal as we are all the time fetching for memory for planes that are not part of selective update. Fix this by adding proper handling for disabling plane selective fetch: If plane previously in part of selective update is now not part of update: Add it into updated planes and let the plane configuration to disable selective fetch for it.
