Subject: [PATCH 1/4] dt-bindings: phy: renesas,usb2-phy: Add clock constraint for RZ/G2L family

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

The RZ/G2L family requires two clocks for USB2 PHY, which are already
defined in the DTSI files. Add a constraint in the DT binding document
to ensure validation with `dtbs_check`.
