dt-bindings: renesas,rcar-dmac: Add r8a779a0 support 



Document the compatible value for the Direct Memory Access Controller
blocks in the Renesas R-Car V3U (R8A779A0) SoC.

The most visible difference with DMAC blocks on other R-Car SoCs is the
move of the per-channel registers to a separate register block.
