dt-bindings: i2c: rcar: Add r8a77470 support

Browse source 
Although the I2C IP found in the RZ/G1C is not exactly the same
as the one found in the R-Car Gen2 family or R-Car Gen3 family,
it can still be considered as compatible with R-Car Gen2 from
a software perpective.
This patch therefore documents the SoC specific compatible string,
and the compatibility with Gen2 fallback is retained.
