This fixes a regression since: 2815ef7fe4d43072b9eda448d04fbc184f2aa513 This motherboard is a strange beast, with an Alpine Ridge thunderbolt controller configured to only do USB with no actual thunderbolt capabilities (Apparently due to the wiring not being thunderbolt compliant).
When runtime PM is enabled in this case, plugging in a USB device results in nothing being detected. Everything works fine when runtime PM is not enabled.
