e1000e: Fix 82579 sets LPI too early.

Enabling EEE LPI sooner than one second after link up on 82579 causes link
issues with some switches.

Remove EEE enablement for 82579 parts from the link initialization flow to
avoid initializing too early.  EEE initialization for 82579 will be done
in e1000e_update_phy_task.
