drm/exynos: Remove crtc->disable

Remove the crtc->disable callback since it's not needed and most likely
incorrect anyways. DRM will fall back to dpms if disable is not defined,
and that will simplify the various paths we have. Furthermore, all
disable did was disable the default overlay on the crtc, which is not
the intended result.

BUG=None
TEST=Tested on snow with boot/hotplug/suspend/idle
