[media] exynos4-is: Fix compilation for !CONFIG_COMMON_CLK

CONFIG_COMMON_CLK is not enabled on S5PV210 platform, so include
some clk API data structures conditionally to avoid compilation
errors. These #ifdefs will be removed for next kernel release,
when the S5PV210 platform moves to DT and the common clk API.
