When adding IS_KABYLAKE definition I didn't included the DC states related because I was planing to include them with the patch that fixes DMC firmware loading, but I forgot them.
Meanwhile this runtime pm code changed a lot for Skylake. Well, I didn't expect that this would crash the machine and I just noticed now that Sarah warned me our driver wasn't working. Thanks Sarah.
