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.

USB xHCI controllers
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.
