pinctrl: sh-pfc: r8a7795: Add I2C pin support
Since pinmuxing for I2C is equal on H3 ES1.0 and later versions, copy the I2C settings from ES1.0. Fixes this error in upstream for Salvator-XS: sh-pfc e6060000.pin-controller: function 'i2c2' not supported sh-pfc e6060000.pin-controller: invalid function i2c2 in map table i2c-rcar: probe of e6510000.i2c failed with error -22 Now, the bus works the same as with other Salvator boards.
