igb: Do not overwrite mdicnfg register when accessing 82580 phy
This change removes the extra configuration we were doing on the mdicnfg register which should be set by EEPROM and which we should not need to write again afterwards. This code was a holdover from some earlier development work that was being done on a board with an incomplete EEPROM and is no longer needed now that the production EEPROMs are in place.
