This patch series starts off with a bug fixes in devfreq code, followed by
refactoring the devfreq code needed for supporting different chipsets, and
ends with adding devfreq support for A6xx.

v2, v3: Addressed review comments from Jordan Crouse.
v4: Patches raised against Rob's msm-next. Fixed a bug caught in downstream
testing.

Note: Scaling works best with these two fixes
