The OF graph should describe physical signals. There is no 'role switch'
signal between Type-C connector and the DWC3 USB controller. Instead
there is a HighSpeed signal lane between DWC3 controller and the USB-C
connector. Rename endpoints in accordance to that (this follows the
example lead by other plaforms, including QRB2210 RB1, QRB4210 RB2 and
all PMIC GLINK platforms).
