[PATCH 2/4] ARM: dts: Exynos5250: add CPU OPP and regulator supply property

[Bartlomiej Zolnierkiewicz]

From: Thomas Abraham <thomas.ab@xxxxxxxxxxx>

For Exynos5250 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 Exynos5250 support from the original patch
- added CPU regulator supply property for Google Spring board
