da850evm: read mac address from I2C EEPROM on AM18x EVM
add support to read mac address for AM18x EVM manufactured from Spectrum digital which have mac address stored in I2C EEPROM manufactured by WINBOND. This patch reads mac address from I2C EEPROM and sets the environment variable if not set, If mac address is already present in environment compare it with the mac address in EEPROM and warn on mismatch.Introduced a config option CONFIG_MAC_ADDR_IN_EEPROM to where to look for the mac address.
