dt-bindings: usb: renesas, usb3-peri: Document RZ/V2M r9a09g011 support 



Document the RZ/V2M SoC bindings.
The RZ/V2M SoC is a little different to the R-Car implementations.
A few DRD related registers and bits have moved, there is a separate
interrupt for DRD, an additional clock for register access and reset
lines for DRD and USBP.
