Subject: [PATCH 7/8] ARM: mvebu: armada-xp: Add I2C eeprom on Lenovo ix4-300d

There is an I2C eeprom connected on Lenovo ix4-300d, add the
corresponding node.

Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@...il.com>

IIRC, the eeprom contains some register init pairs (address, data) for
and is empty otherwise. I'll have to check the boot loader code again,
but (again) IIRC, stock u-boot already does the sequence in code and
ignores the eeprom.
