dmaengine: usb-dmac: Add compatible string for r8a7743/5
This patch adds support for r8a7743/5 SoCs. The Renesas RZ/G1[ME] (R8A7743/5) usbdmac engine is identical to the R-Car Gen2 family. No driver change is needed due to the fallback compatible value "renesas,r8a7743-usb-dmac". Adding the SoC-specific compatible values here has two purposes: 1. Document which SoCs have this hardware module, 2. Allow checkpatch to validate compatible values.
