With this patch series, Kernel booting is halted at end of kernel
booting. I tested this patch series on Trats2 board based on Exynos4412 SoC.
Below is a part of full booting logs, which was halted,
[ 1.992015] exynos-drm-ipp exynos-drm-ipp: drm ipp registered
successfully.
[ 1.993009] exynos-drm exynos-drm: bound exynos-drm-vidi (ops

After that, I tested it again without FIMD and the booting is ok. So I
guess that this atomic feature has a bug to FIMD driver.
