These patches fix a bug concerning an access issue to display controler (ltdc) registers. If the physical layer of the DSI is started too early then the fifo DSI are full very quickly which implies ltdc register's access hang up. To avoid this problem, it is necessary to start the DSI physical layer only when the bridge is enable.
