lan78xx: Use default values loaded from EEPROM/OTP after reset
Use default value of auto duplex and auto speed values loaded from EEPROM/OTP after reset. The LAN78xx allows platform configurations to be loaded from EEPROM/OTP. Ex: When external phy is connected, the MAC can be configured to have correct auto speed, auto duplex, auto polarity configured from the EEPROM/OTP.
