MPU and CORE should stay awake if there is CAM domain ACTIVE. This is
because that module doesn't have wake-up capability.

The original patch was written by Jouni Högander in 2008 and this is the

I wonder if the approach taken in the patch is valid these days;
nevertheless it seems to do the job...
