This patch adds dvfs support for exynos5440 SOC. This soc has 4 cores and they scale at same frequency. The nature of exynos5440 clock controller is different from previous exynos controllers so not using the common exynos cpufreq framework. The major difference being interrupt notification for frequency change. Also, OPP library is used for device tree parsing to get different parameters like frequency, voltage etc. Since the opp library sorts the frequency table in ascending order so they are again re-arranged in descending order. This will have one-to-one mapping with the clock controller state management logic.
