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.

   It's called RZ/G1.
