Bug description:
[Impact]
Intel I219 ethernet stops working after system sleep.
[Fix]
Force resume Intel ME to fix I219. It's not surprising because ME/AMT is
controlled through Intel I219.
[Test]
Use `ping 1.1.1.1` to test if I219 is still alive. With the patch
applied, the ethernet can survive several system sleeps.
[Where problems could occur]
The commit essentially disables direct-complete optimization, so it
will make system suspend/resume slightly slower.
