e1000e: WoL can fail on 82578DM
During suspend, the PHY must be reset for workaround updates to take effect
without restarting auto-negotiation. Also, set the disable GbE and enable
Low Power Link Up (LPLU) if the EEPROM is configured to do likewise in
either D0 or non-D0a instead of just the latter.
