spi: dt-bindings: renesas,rspi: Document RZ/Five SoC

The RSPI block on the RZ/Five SoC is identical to one found on the RZ/G2UL
SoC. "renesas,r9a07g043-rspi" 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,rspi-rz" will be used as a fallback on RZ/Five SoC.
