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.

Signed-off-by: Amit Daniel Kachhap <amit.daniel@samsung.com>

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