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.
