clk/exynos4: Fix compilation warning

Fixes the following warning:
WARNING: drivers/built-in.o(.text.unlikely+0x2c50): Section mismatch in reference from the function exynos4_clk_sleep_init() to the (unknown reference) .init.data:(unknown)
   The function exynos4_clk_sleep_init() references
   the (unknown reference) __initdata (unknown).
   This is often because exynos4_clk_sleep_init lacks a __initdata
   annotation or the annotation of (unknown) is wrong.
