[media] exynos4-is: Simplify sclk_cam clocks handling
Use clk_prepare_enable()/clk_disable_unprepare() instead of separately prearing/unparing the clk_cam clocks. This simplifies the code that is now mostly not going to be used, function __fimc_md_set_camclk() is only left for S5PV210 platform which is not yet converted to Device Tree.
