But dmc firmware is required even earlier (namely for the skl power well 2). Hence we need to grab a rpm reference higher up in the hierarchy. For simplicity just grab the _INIT display power well. That's a bit too much, but since the firmware loading task should completely fairly quickly this won't be a real problem really.
