clk: exynos4: Use mout_mpll_user_* on Exynos4x12
Browse files Browse the repository at this point in the history 
Many clock muxes of Exynos 4x12 uses mout_mpll_user_* clocks instead of
sclk_mpll as one of their parents.

This patch moves such clocks from common array into SoC-specific arrays
and adjusts their parent lists respectively.
