dt-bindings: usb: renesas,usbhs: Add RZ/G3E SoC support

Document the Renesas USBHS controller found on the Renesas RZ/G3E SoC.
The USBHS block on RZ/G3E is functionally identical to the one found
on the RZ/G2L family, so no driver changes are needed. The existing
"renesas,rzg2l-usbhs" fallback compatible will continue to be used for
handling this IP.
