[Arm-netbook] [EOMA68] changes to I2C EEPROM address location

i've updated the specification to reflect what's actually been
deployed on the flying squirrel pcb.  apologies but i'd read the
AT24C64 datasheet incorrectly: the "1" in the 8-bit MSB of an I2C
address is not counted in the address so i'd read it as "0xA2" when it
should be "0x51".

apologies but all boards currently being designed will need to update
schematics to match accordingly.
