[PATCH 4/6] ARM: dts: Exynos4210: add CPU OPP and regulator supply property

[Bartlomiej Zolnierkiewicz]

From: Thomas Abraham <thomas.ab@xxxxxxxxxxx>

For Exynos4210 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:
- removed Exynos5250 and Exynos5420 support for now
