width still exceeds width limit.

The content of every half of screen is sent out via one interface in
dual-DSI case. The content for every interface is blended by a LM
pair, thus no content of any pipe shall cross the LM pair. We need
to clip plane into pipes per left and right half screen ROI if topology
is quad pipe.
