Document the Renesas USBHS controller found on the Renesas RZ/V2N (R9A09G056) SoC. The USBHS block on RZ/V2N is functionally identical to the one on the RZ/G2L family, so no driver changes are needed. The existing "renesas,rzg2l-usbhs" fallback compatible will continue to be used for handling this IP.
