Document the Renesas USBHS controller found on the Renesas RZ/V2H(P) SoC.
The USBHS block on RZ/V2H(P) 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.

In addition, update the schema validation logic by replacing the enum list
of SoC-specific compatibles with a const "renesas,rzg2l-usbhs" as all
listed SoCs share identical USBHS hardware and already include the fallback
compatible. This will help to simplify the schema and avoid redundancy.
