usb: host: xhci-plat: add R-Car Gen2 and Gen3 fallback compatibility strings 



Add fallback compatibility strings for R-Car Gen2 and Gen3.

This is in keeping with the fallback scheme being adopted wherever
appropriate for drivers for Renesas SoCs.

Required properties:

  - compatible: should be one of "generic-xhci",

    "marvell,armada-375-xhci", "marvell,armada-380-xhci",

    "renesas,xhci-r8a7790", "renesas,xhci-r8a7791", "renesas,xhci-r8a7793",

    "renesas,xhci-r8a7795" (deprecated: "xhci-platform").

  - compatible: should be one or more of



    - "generic-xhci" for generic XHCI device

    - "marvell,armada-375-xhci" for Armada 375 SoCs

    - "marvell,armada-380-xhci" for Armada 38x SoCs

    - "renesas,xhci-r8a7790" for r8a7790 SoC

    - "renesas,xhci-r8a7791" for r8a7791 SoC

    - "renesas,xhci-r8a7793" for r8a7793 SoC

    - "renesas,xhci-r8a7795" for r8a7795 SoC

    - "renesas,rcar-gen2-xhci" for a generic R-Car Gen2 compatible device

    - "renesas,rcar-gen3-xhci" for a generic R-Car Gen3 compatible device

    - "xhci-platform" (deprecated)



    When compatible with the generic version, nodes must list the

    SoC-specific version corresponding to the platform first

    followed by the generic version.



  - reg: should contain address and length of the standard XHCI

    register set for the device.

  - interrupts: one XHCI interrupt should be described here.
