Subject: [PATCH] dt-bindings: reset: renesas,rzv2h-usb2phy: Document RZ/V2N SoC support

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Document support for the USB2PHY reset controller found on the Renesas
RZ/V2N (R9A09G056) SoC. The reset controller IP is functionally identical
to that on the RZ/V2H(P) SoC, so no driver changes are needed. The existing
`renesas,r9a09g057-usb2phy-reset` compatible will be used as a fallback
for the RZ/V2N SoC.
