[Impact]
Some ThinkPads failed to suspend to s2idle when ethernet disconnected.

[Fix]
I219 chip of some platforms is controlled by ME, which needs more time
when setting ULP mode. Wait for ME to finish setting ULP mode.

[Test]
Verified on hw, and user reported s2idle works.

[Regression Potential]
Low, Increase timeout and breaks with condition,
no impacts for who don't need this long wait.

Bionic doesn't introduce the commit f15bb6dde738cc8fa0, no need for
this.
