The patch series removes the use of Exynos specific cpufreq driver and enables
the use of cpufreq-cpu0 driver for Exynos4210, Exynos4x12 and Exynos5250 based
platforms. This is being done for few reasons.

(a) The Exynos cpufreq driver reads/writes clock controller registers
    bypassing the Exynos CCF driver which is sort of problematic.
(b) Removes the need for having clock controller register definitions
    in the cpufreq driver and also removes the need for statically
    io-remapping clock controller address space (helps in moving towards
    multiplatform kernel).
Thanks a lot for your continued effort. Looks great overall, but I have one
comment about the general way the cpu0 cpufreq driver works, not specific
to the exynos implementation. See my reply to patch 4.
