So powertop can be changed to show RC6p and RC6pp only on the platforms they are available. v2: Simplify by merging RC6p and RC6pp groups and respect the spec that mentions deep and deepest RC6 on SNB and IVB although they keep disabled by default. v3: Remove unecessary space. v4: RC6p and RC6pp is only for SNB and IVB; unify debug msg and use has_rc6p() on sanitize options instead of is gen 6 and ivb. v5: yet another fix on has_rc6p macro. final is_gen6 or is_ivb! To make sure we are excluding hsw and baytrail.

Patch merged on intel-gpu-tools mater.
