exynos5420: Setup clocks for MMC bus controller.
To configure source clocks on Exynos 5420 for MMC drivers.
Some registers are different from the 5250. FSYS now has two parts
and MMC uses FSYS2. The MMC block uses MPLL as the clock source.
The "high-speed" MMC interface runs as 52MHz, so divider is set
accordingly.
Also, the MMC driver has changed from MSHCI (Mobile Storage Host Controller
Interface) to DWMCI (DesignWare MMC Controller Interface).
