Add the code to set the ethernet mac address from eeprom by using the common code from the common folder.
Signed-off-by: Wenyou Yang wenyou.yang@microchip.com ---
Changes in v2: - Add a new patch to create board/$(VENDOR)/common folder to accommodate the common code and put the code to set the ethernet mac address from eeprom here. - Use the i2c_eeprom driver to read the mac address, instead of the dm i2c API directly.
