This patch adds the support for CMU (Clock Management Units) of Exynos5433 which is 64bit SoC and has Octa-cores. This patch supports necessary clocks (PLL/MMC/UART/MCT/I2C/SPI) for kernel boot and includes binding documentation for Exynos5433 clock controller.

nit: Just for consistency, all these offset should be in small case.
