[U-Boot] [PATCH 2/2] ARM: UniPhier: set I2C offset length of on-board EEPROM in DTS

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.
