ARM: UniPhier: move EEPROM device node into a separate DTS This EEPROM chip is installed on the expansion board commonly used on UniPhier platform. To avoid duplicated description, move the EEPROM node to a separate file and include it from other device tree sources.

ARM: dts: UniPhier: add device-specific compatible string for EEPROM For the record, describe exactly which device of which vendor is used on this board. I2C EEPROM is bound by the generic compatible string, "i2c-eeprom", so this commit has no impact on the functionality.

ARM: UniPhier: set I2C offset length of on-board EEPROM in DTS 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.
