Each port has a 'reg' property embedded. This property will be wrongly interpretted by the MIPI DSI bus driver, because the driver will take each subnode which contains a 'reg' property as a DSI peripheral device. This patch moves the existing MIPI DSI ports into a new 'ports' node so that the MIPI DSI bus driver may distinguish its DSI peripheral device(s) from the existing ports.
