Bug Description
[Impact]
Some USB devices aren't working if they are plugged under system sleep.
[Fix]
Consider xHCI PORTSC CAS bit over other conditions.
[Test]
Plug or re-plug USB devices during system sleep. USB devices always work
after system resume.
[Regression Potential]
There could be devices that depends on the old (but wrong) behavior.
However it's really unlikely and it's against xHCI spec, we can deal
with those quirky devices if any.
