From: Thomas Abraham <thomas...@samsung.com>
For Exynos5420 platforms, add CPU operating points for
migrating from Exynos specific cpufreq driver to using
generic cpufreq driver.
Changes by Bartlomiej:
- split Exynos5420 support from the original patch
Changes by Ben Gamari:
- Port to operating-points-v2
