Add support for the ON Semiconductor NB7VPQ904M Type-C USB SuperSpeed and DisplayPort ALT Mode Linear Redriver chip found on some devices with a Type-C port. The redriver compensates ultra High-Speeed DisplayPort and USB Super Speed signal integrity losses mainly due to PCB & transmission cables. The redriver doesn't support SuperSpeed lines swapping, but can support Type-C SBU lines swapping. Support is designed as a Type-C Switch and Mux, and can propagate orientation settings to the source endpoint, which is usually a Super Speed PHY which does the data lanes swapping. Bindings are added first and can handle the fact data lanes pairs can be swapped on the PCB.
