Exynos4210 and Exynos4x12 SoCs have the PL330 MDMA IP block clock
defined exactly in same way in documentation. Using different
names for these clocks is a bit misleading. Since there is no users
of CLK_MDMA2 in existing dts files this patch drops CLK_MDMA2 and
replaces it with CLK_MDMA in the driver. This ensures PL330 MDMA
has correct clock assigned on Exynos4x12 SoCs.
