e1000e: PCIm function state support
Due to commit: 5d8682588605 ("[misc] mei: me: allow runtime
pm for platform with D0i3")
When disconnecting the cable and reconnecting it the NIC
enters DMoff state. This caused wrong link indication
and duplex mismatch. This bug is described in:
https://bugzilla.redhat.com/show_bug.cgi?id=1689436
Checking PCIm function state and performing PHY reset after a
timeout in watchdog task solves this issue.
