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



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.

compatible: "renesas,pcie-r8a7779" for the R8A7779 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>
