PCI: rcar: Add gen2 fallback compatibility string for pcie-rcar

Browse Source 
Add fallback compatibility string for R-Car Gen 2 family.  This is in
keeping with the fallback scheme being adopted wherever appropriate for
drivers for Renesas SoCs.

* Renesas RCar PCIe interface
Required properties:
- compatible: should contain one of the following
"renesas,pcie-r8a7779", "renesas,pcie-r8a7790", "renesas,pcie-r8a7791",
"renesas,pcie-r8a7795"
compatible: "renesas,pcie-r8a7779" for the R8A7779 SoC;
"renesas,pcie-r8a7790" for the R8A7790 SoC;
"renesas,pcie-r8a7791" for the R8A7791 SoC;
"renesas,pcie-r8a7795" for the R8A7795 SoC;
"renesas,pcie-rcar-gen2" for a generic R-Car Gen2 compatible device.
When compatible with the generic version, nodes must list the
SoC-specific version corresponding to the platform first
followed by the generic version.
- reg: base address and length of the pcie controller registers.
- #address-cells: set to <3>
- #size-cells: set to <2>
