ravb: add fallback compatibility strings

Browse source 
Add fallback compatibility strings for R-Car Gen 2 & 3 SoC Families.
This is in keeping with the fallback scheme being adopted wherever appropriate
for drivers for Renesas SoCs.

- compatible: "renesas,etheravb-r8a7790" if the device is a part of R8A7790 SoC.
"renesas,etheravb-r8a7794" if the device is a part of R8A7794 SoC.
"renesas,etheravb-r8a7795" if the device is a part of R8A7795 SoC.
"renesas,etheravb-rcar-gen2" for generic R-Car Gen 2 compatible interface.
"renesas,etheravb-rcar-gen3" for generic R-Car Gen 3 compatible interface.
When compatible with the generic version, nodes must list the
SoC-specific version corresponding to the platform first
followed by the generic version.
- reg: offset and length of (1) the register block and (2) the stream buffer.
- interrupts: A list of interrupt-specifiers, one for each entry in
interrupt-names.
