The reason it existed in the first place was to make up for the mixture of display/overlay/manager ops being spread across hdmi and mixer. With that code now rationalized, mixer and hdmi map directly to exynos_drm_crtc and exynos_drm_encoder, respectively. Since there is a 1:1 mapping, we no longer need this layer.
