[Impact]
Plugging ethernet cable doesn't work on new I219 after it runtime
suspends to D3.

[Fix]
Intel confirms that it only supports D0, so disable runtime power
management to prevent it from entering D3.

[Test]
Once the patch applied, the device always stays at D0, which doesn't
have this problem.

[Regression Potential]
Low. This doesn't introduce any functional change.
