The EEPROM chip on the UniPhier reference daughter board expects 2-byte offset address.
Since 7132b9fd68a1 (dm: i2c: dts: Support an offset-len device tree property), I2C sub-nodes can have "u-boot,i2c-offset-len" property.
It is convenient to set the default I2C offset address length in Device Tree, so that we do not have to set it on the command line.
