For Exynos 4210/5250/5420 based platforms, add CPU operating points and CPU regulator supply properties for migrating from Exynos specific cpufreq driver to using generic cpufreq drivers.

Tested the series on a Exynos5420 based Peach Pit Chromebook by doing the following for CPU0-3: 1) Verified that the big.LITTLE CPUFreq (arm-big-little) driver was reported as used in /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver. 2) Set all available governors (conservative, ondemand, userspace, powersave and performance). 3) Confirmed that cpuinfo_cur_freq and scaling_cur_freq values were fixed or changing according to the selected governor policy. 4) Verified that the statistics in /sys/devices/system/cpu/cpu*/cpufreq/stats/* were filled. Everything is working correctly so please feel free to add for the whole series: Tested-by: Javier Martinez Canillas <redacted> Best regards, Javier
