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.
