This patch adds the mux/divider clocks for CMU_CDREX (DRAM Express
Controller) which generates the clocks for DRAM and NoC (Network on Chip) bus
clock. But, there is differnet source of MUX_MX_MSPLL_CCORE between exynos5420
and exynos5422. So, each MUX_MX_MSPLL_CCORE uses the different parent source
group.
