i2c: rcar: Add R-Car Gen4 support
[ Upstream commit ea01b71b07993d5c518496692f476a3c6b5d9786 ]
Add support for the I2C Bus Interface on R-Car Gen4 SoCs (e.g. R-Car
S4-8) by matching on a family-specific compatible value.
While I2C on R-Car Gen4 does support some extra features (Slave Clock
Stretch Select), for now it is treated the same as I2C on R-Car Gen3.
