dt-bindings: phy: renesas,usb2-phy: Document RZ/V2H(P) SoC

Document USB2.0 phy bindings for RZ/V2H(P) ("R9A09gG57") SoC.

RZ/V2H(P) USB2.0 phy is similar to one found on the RZ/G2L SoC, but it
needs additional configuration to be done as compared RZ/G2L USB2.0 phy.
To handle this difference a SoC specific compat string is added for
RZ/V2H(P) SoC.

Like the RZ/G2L SoC, the RZ/V2H(P) USB2.0 PHY requires the `resets`
property and has two clocks.
