drm/exynos: Fix suspend/resume support
Commit 7d902c05b480 ("drm: Nuke drm_atomic_helper_connector_dpms")
removed drm_atomic_helper_connector_dpms() helper saying that it was a dead
code. It was however indirectly used by Exynos DRM driver for implementing
suspend/resume support. To fix this regression (after that patch Exynos DRM
suspend/resume functions became no-ops and hardware fails to suspend),
this patch rewrites them with drm_atomic_helper_suspend/resume() helpers.
Fixes: 7d902c05b480 ("drm: Nuke drm_atomic_helper_connector_dpms")
