usb: typec: add support for the nb7vpq904m Type-C Linear Redriver

Browse source

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.
