drm/exynos: fix waiting pageflip on i80 panel
If panel is use i80 interface, encoder should wait to complete prior
pageflip before encoder disables panel because te interrupt is happened
by panel.
Upstream Exynos DRM driver doesn't need this because Exynos atomic
commit procedures already does this job of waiting for pending updates
to finish. Refer the commit c4533665d819 ("drm/exynos: wait all planes
updates to finish") applied from v4.3-rc1
