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.y...@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.
