dt-bindings: usb: renesas,usbhs: Document RZ/Five SoC

The USBHS IP block on the RZ/Five SoC is identical to one found on the
RZ/G2UL SoC. "renesas,usbhs-r9a07g043" compatible string will be used on
the RZ/Five SoC so to make this clear and to keep this file consistent,
update the comment to include RZ/Five SoC.

No driver changes are required as generic compatible string
"renesas,rza2-usbhs" will be used as a fallback on RZ/Five SoC.
