dt-bindings: reset: renesas,rzg2l-usbphy-ctrl: Document RZ/Five SoC

The USBPHY Control Device on the RZ/Five SoC is identical to one found on
the RZ/G2UL SoC. "renesas,r9a07g043-usbphy-ctrl" 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,rzg2l-usbphy-ctrl" will be used as a fallback on RZ/Five SoC.
