The CANFD block on the RZ/Five SoC is identical to one found on the
RZ/G2UL SoC. "renesas,r9a07g043-canfd" compatible string will be used
on the RZ/Five SoC so to make this clear, update the comment to include
RZ/Five SoC.

No driver changes are required as generic compatible string
"renesas,rzg2l-canfd" will be used as a fallback on RZ/Five SoC.
