[V3,4/4] dts: Add cpufreq controller node for Exynos5440 SoC

Commit Message

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.

Changes in V3:
* Moved the DT node outside cpu0 node as the driver is now a platform
  driver.
