dt-bindings: net: renesas,etheravb: Document RZ/Five SoC

The Gigabit Ethernet IP block on the RZ/Five SoC is identical to one
found on the RZ/G2UL SoC. "renesas,r9a07g043-gbeth" 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-gbeth" will be used as a fallback on RZ/Five SoC.
