clk: samsung: Change signature of exynos5_subcmus_init() function

In order to make it easier in subsequent patch to create different subcmu
lists for exynos5420 and exynos5800 SoCs the code is rewritten so we pass
an array of pointers to the subcmus initialization function.

Fixes: b06a532b ("clk: samsung: Add Exynos5 sub-CMU clock driver")
