I assume H/W team stop exposing these counter as I can not see DC5/DC6 counter details for other platform other than gen9(skl/bxt). Not sure is it ok to rely on something which is not confirmed.

There is no confirmation if the DC5 to DC6 is available on CNL though. But I could see DC3 to DC5 counter increasing reliably. So let's at least add this one.
