Subject: [PATCH] dt-bindings: dma: rz-dmac: Document RZ/Five SoC

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

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