Despite the name, R-Car V3U is the first member of the R-Car Gen4
family. I2C on R-Car V3U also supports some extra features (e.g. Slave
Clock Stretch Select), which are supported by other R-Car Gen4 SoCs, but
not by any other R-Car Gen3 SoC.
Hence move its compatible value to the R-Car Gen4 section.
