From: Thomas Abraham <thomas.ab@samsung.com>

For Exynos5420 platforms, add CPU operating points and CPU
regulator supply properties 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
