* Added OPP library support to parse DT
This patch helps to have single binary for exynos5440 and previous
exynos soc's. This change is needed for adding exynos5440 cpufreq driver
which does not uses exynos-cpufreq common file and adds it own driver.

This patch adds support for CPU hotlpug for the 3 secondary cores
of the exynos5440 SOC. The command to hotplug out/in is,
echo 0 > /sys/devices/system/cpu/cpu[1-3]/online
echo 1 > /sys/devices/system/cpu/cpu[1-3]/online

Add cpufreq controller device node for Exynos5440 SoC for passing
parameters like controller base address, interrupt and cpufreq
table. This node is added outside cpu0 as this driver is now a platform
driver and a new device structure is needed.

ARM: EXYNOS: Move arm core power down clock to exynos5250 common
clock
ARM: SAMSUNG: Add SAMSUNG_PM config option to select pm
ARM: EXYNOS: cpuidle: Allow C1 state only in supported
Now with common clock support added for exynos5250 it is necessary to move
this code to exynos5250 common clock driver as clock registers should be
handled there. This change is tested in exynos5250 based arndale platform.

This patch registers the basic C0 state for all exynos SOC's but
limits the C1(AFTR -Arm off top running) state in only the supported
SOC's(ie. EXYNOS 4210, 4212, 4412 and 5250).
