Found the bug, but still only read the msr once every second - mainly as
an exercise in handling different sample rates.

baa5be07d6 overlay: Add rc6 residency 
Not much point at the moment since we use forcewake to continuously
probe the GPU busyness. But that will eventually change to a more
power-efficient in-kernel.

f185f46114 overlay: Correct layout of ring/seqno in raw sample 
For seqno completion, the events are too coarse i.e. one event may
signal the completion of a few seqno. We will need to sort the events to
properly compute the busy times.

6233cac9c9 overlay: Couple wait begin/end events together to fix accounting 
Since the events may be processed out of order (due to per-cpu
ringbuffers) we need to be careful to associated wait pairs in order to
compute the correct elapsed time.

mmapping it directly - but the target must already be mmapped.
