add support to read mac address for AM18x EVM manufactured from
Spectrum digital which have mac address stored in I2C EEPROM manfactured
by WINBOND. This patch reads mac address from I2C EEPROM and updates
environment variable if not set. Introduced a config option
CONFIG_MAC_ADDR_IN_EEPROM to where to look for the mac address.
