With this patch, it causes below error at the DP driver because fimd 
clock is disabled.

[    0.210000] exynos-dp exynos-dp: Timeout of video streamclk ok
[    0.210000] exynos-dp exynos-dp: unable to config video
[    0.210000] exynos-dp: probe of exynos-dp failed with error -110

I wonder fimd clock has any dependency with DP

Thanks.
