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).

This patch adds device node for TMU controller. There are 3
instances of the controllers so 3 nodes are created.

frequency clipping limits. Because of such differences with the existing 4210
tmu controller, exynos5440 tmu driver is added in a new file.

This code changes the zone handling to use the trip count passed
by the TMU driver. This also helps in adding more zone support.

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.

cpufreq: exynos: Add cpufreq driver for exynos5440
cpufreq
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.
