This series fixes a RC6 bug at HSW that can impact its performance. At my fiurst attempt I noticed more than 1W saved, but I didn't measured this lates series yet.
Also there are 2 clean ups patches that removes unecessary registers and bits set for HSW. The latest patch is optional. It splits hsw_enable_rps to make it more clean since the gen6_enable_rps was becoming a mess full of IS_HASWELL and probably becoming worse with new upcoming platforms.
