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

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

For Exynos4210 platforms, add CPU operating points and CPU
regulator supply properties for migrating from Exynos specific
cpufreq driver to using generic cpufreq driver.
