Subject: [PATCH] dt-bindings: phy: renesas,usb2-phy: Document RZ/V2N SoC support

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

Document support for the USB2.0 phy found on the Renesas RZ/V2N
(R9A09G056) SoC. The USB2.0 phy is functionally identical to that on the
RZ/V2H(P) SoC, so no driver changes are needed. The existing
`renesas,usb2-phy-r9a09g057` compatible will be used as a fallback
for the RZ/V2N SoC.
