This patchset is based on exynos-drm-next-todo branch of Inki Dae's tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git

I have just put up Rob's and Sean's idea of chaining up the bridges
in code, and have implemented basic panel controls as a chained bridge.
This works well with ptn3460 bridge chip on exynos5250-snow board.

Still need to make use of standard list calls and figure out proper way
of deleting the bridge chain. So, this is just a rough version.
