Public bug reported:

[Impact]
Intel I219 ethernet on several HP workstations has a chance to stop
working after S3.

[Fix]
Increase polling timeout on MDIC ready bit so we wait a bit longer for 
Intel ME.

[Test]
Without the fix, the I219 ethernet breaks in 10 S3 cycle.
With the fix applied, the ethernet keeps working after 1000+ S3 stress
test.

[Regression Potential]
If the firmware/hardware is _really_ broken, we'll waste a bit more time
to wait the device resume. Otherwise no functional change.
