====================
Keep PHY link during WoL sleep cycle

First we divide the init/deinit path to allow for a partial init/deinit
during a sleep cycle. We also remove some unnecessary small functions at
the same time.

Then we modify the suspend and resume path to allow for a partial bring
down and bring up. This allow us to keep the PHY link up and to resume
network traffic much quicker. Note we only do this when WoL is enabled
since the PHY is already powered. In the non-WoL case we want to follow
the same flow.
