With this policy we have to indicate scaling change when plane clip is updated in case plane clip change causes MPO plane to go in or out current ODM slice. With new ODM + MPO policy we allocate pipe independent from plane clip size so we no longer treat it as a scaling change. There no need to do a full update due to clip size change anymore.
