Merge branch 'exynos-drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git...

Since HW trigger mode was suppoted we have faced with a issue
that Display panel didn't work correctly when trigger mode was changed
in booting time.
For this, we keep trigger mode with SW trigger mode in default mode
like we did before.

However, we will need to consider PSR(Panel Self Reflash) mode to resolve
this issue fundamentally later.
