ARM: mmp: Replace <linux/clk-provider.h> by <linux/of_clk.h> The Marvell MMP platform code is not a clock provider, and just needs to call of_clk_init(). Hence it can include <linux/of_clk.h> instead of <linux/clk-provider.h>.

ARM: appropriate __init annotation for const data Init data marked const should be annotated with __initconst for correctness and not __initdata. In some cases the array gathering references to that data has to be marked const as well. This fixes LTO builds that otherwise fail with section mismatch errors.
