with this patch series, exynos_drm_encoder_dpms() will call apply
callback to set local overlay data to real hardware registers and
exynos_drm_crtc_dpms() will be used to enable/disable fimd or hdmi
power(clock and regulator). actually, previous codes called mode_set
two times so this could make it messed up other display sub devices
such as mDNIe.
