[media] exynos4-is: Add support for all required clocks 



This patch adds 3 more clocks to Exynos4 ISP driver. Enabling them is
needed to make the hardware operational. Till now it worked only because
those clocks were registered with IGNORE_UNUSED flag and were enabled
by default after SoC reset.
