drm/exynos: fix overlay updating issue
Chagelog v2:
Move encoder's dpms updating into exynos_drm_encoder_commit
function because when crtc's dpms is updated, encoder's dpms
is updated also. This would induce the issue that encoder
isn't disabled after crtc is disabled.
Changelog v1:
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.
