New issues that were discovered while making the tests work on Gen8+ :

 - we need to measure timings between periodic reports and discard all
   other kind of reports

 - it seems periodicity of the reports can be affected outside of RC6

   clock cycles per timestamp deltas
I think this would be easier to review if we split this into two patches...

Also, somewhat worrying is that I've yet to see the oa-exponents test
pass on my BDW machine.
