exynos_drm_manager is used by internal Exynos DRM framework for representing crtc. As it should be mapped 1:1 to vidi private context it seems more reasonable to embed it directly in that context. As a result further code simplification will be possible. Moreover it will be possible to handle multiple mixer devices in the system.
