The EEPROM chips on UniPhier reference daughter boards expect 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.
