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: re-license device tree files under GPLv2+/X11 The current GPL only licensing on the device trees makes it very impractical for other software components licensed under another license. To make it easier to reuse them, the device trees for UniPhier SoCs and boards have already been dual-licensed in Linux. Follow this trend in U-boot too.

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.
