It currently hardcodes the local port number to 0, which breaks any output with a different port number (SDI on OMAP3 and any DPI output but the first one). Fix this by repurposing the currently unused of_ports bitmask in omap_dss_device with an of_port output port number, and use it to traverse the OF graph.
