clk: samsung: exynos4415: Add clocks using common clock framework

This patch adds clock driver of Exynos4415 SoC based on Cortex-A9 using
common clock framework. The CMU (Clock Management Unit) of Exynos4415
controls PLLs(Phase Locked Loops) and generates system clocks for CPU,
busses and function clocks for individual IPs.
