dt-bindings: PCI: rcar: Add device tree support for r8a7743
Add support for r8a7743. The Renesas RZ/G1M(R8A7743)PCIe controller is identical to the R-Car Gen2 family. No driver change is needed due to the fallback compatible value "renesas,pcie-rcar-gen2". Adding the SoC-specific compatible values here has three purposes: 1. Document which SoCs have this hardware module, 2. Allow checkpatch to validate compatible values. 3. Allow the driver to support SoC specific implementations in future as necessary.
