Add device tree binding support for the USB3.2 Gen2 controller on Renesas RZ/V2H(P) and RZ/V2N SoCs. The USB3.2 IP on these SoCs is identical to that found on the RZ/G3E SoC. Add new compatible strings "renesas,r9a09g056-xhci" for RZ/V2N and "renesas,r9a09g057-xhci" for RZ/V2H(P). Both variants use "renesas,r9a09g047-xhci" as a fallback compatible to indicate hardware compatibility with the RZ/G3E implementation. Update the title to be more generic as it now covers multiple SoC families beyond just RZ/G3E.
