ASoC: dt-bindings: renesas,rz-ssi: Document RZ/Five SoC

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