Current Cortina phy driver assumes that firmware upload is required during initialization and is dependent on presence of corresponding macros like CONFIG_CORTINA_FW_ADDR for compilation. But Cortina phy has provision to store phy firmware in attached dedicated EEPROM. And boards designed with such EEPROM does not require firmware upload. Add CORTINA_NO_FW_UPLOAD option in cortina.c to support such boards.
