[PATCH] drm/exynos: fix overlay updating issue

[Inki Dae]

This patch fixes a issue that overlay data aren't applied
to real hardware when dpms off goes to on after setcrtc
was requested like below,
    dpms off -> setcrtc -> dpms off -> dpms on

For this, it makes encoder's dpms to be updated when
setcrtc is requested.
