tools/power turbostat: Baytrail c-state support

Browse Source 
The Baytrail SOC, with its Silvermont core, has some unique properties:

1. a hardware CC1 residency counter
2. a module-c6 residency counter
3. a package-c6 counter at traditional package-c7 counter address.

The SOC does not support c3, pc3, c7 or pc7 counters.
