Bug description:
[Impact]
Pericom EHCI/OHCI USB Controller can't detect hotplug event when it's runtime-suspended, due to its unreliable PME#.

[Fix]
Disable PME for all its power state since all of them don't work reliably.

[Test]
Hotplugging event can be reliably detected by the device, after the fix gets applied.

[Regression Potentia]
Low. This targets specific device, without touching any logic.
