dt-bindings: usb: renesas,usb-xhci: Document RZ/V2M support 



Document the RZ/V2M SoC bindings.
The RZ/V2M SoC is a little different to the R-Car implementations.
You can access the registers associated with the currently set DRD mode,
therefore as part of init, we have to set the DRD mode to host.
