In this case it's an xHC device, which can't be woken up by plugging USB device. [Test] With the patch, the xHC no longer get put to suspend incorrectly. USB devices can work on the xHC now. [Fix] We need to check if the device is power managed by system firmware, also if it supports PME from D3hot. [Regression Potential] Low. It fixes a regression caused by the PM core refactor.
