Subject: [PATCH] ARM: dts: Exynos4210: add CPU OPP and regulator supply
 property

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
