arm64: dts: rockchip: add USB-C support for ROCK 5B/5B+/5T

Browse Source 
Add hardware description for the USB-C port in the Radxa ROCK 5 Model B
family. This describes the OHCI, EHCI and XHCI USB parts. The DisplayPort
AltMode is only partially described, as bindings for the necessary
DisplayPort controller are still being reviewed.
