e1000e: reorganize PHY and flow control interface

Browse Source 
This reorganization moves the PHY status into a separate
struct. Flow Control setup is moved into this struct as well
and frame size away from here into the adapter struct where its
inly use is.

The post-link-up code is now a separate function and moved out
of the watchdog function itself. This allows us to track the
es2lan restart issue a bit easier.
