Bug Description
[Impact]
Dell Precision 5550 cannot detect Thunderbolt device hotplug.
[Fix]
Refresh ACPI wakeup power if it's already enabled to make GPE work.
[Test]
Make sure the root port of TBT hierachy is in D3cold.
Plug a Thunderbolt Dock or Thunderbolt Disk, the system cannot detect
anything.
With the patch applied, OS can always detect hotplugged Thunderbolt
devices.
[Where problems could occur]
Though we refresh the wakeup device power, we didn't disable/enable ACPI
GPEs, so we won't miss any GPE event from this fix.
