[PATCH] clk: exynos4: export clocks required for fimc-is

This patch adds clock indexes for ACLK_DIV0, ACLK_DIV1,
ACLK_400_MCUISP, ACLK_MCUISP_DIV0, ACLK_MCUISP_DIV1,
DIVACLK_400_MCUISP and DIVACLK_200 so these clocks are
available to the consumers (Exynos4x12 FIMC-IS subsystem).
While at it, indentation of the mux clocks table is
corrected.
