Exynos4212/4412 has different clock for the PL330 MDMA, ensure
the clock is properly assigned for these newer SoCs.

Since the ID for CLK_MDMA2 was added mistakenly, instead of reusing 
CLK_MDMA and it was not used by any device tree files anyway, I believe 
the better fix would be to simply change the clock definition in Exynos 
4 clock driver to use CLK_MDMA for both SoC families.

Best regards,
Tomasz
