test: Load mac address with i2c eeprom
This uses an i2c eeprom to load a mac address using the nvmem interface. Enable I2C_EEPROM for sandbox SPL since it is the only sandbox config which doesn't enable it eeprom. Signed-off-by: Sean Anderson <sean.anderson@seco.com> Reviewed-by: Simon Glass <sjg@chromium.org>
