drm/exynos/dsi: register connector if it is created after drm bind 



DSI device can be attached after DRM device is registered. In such
case newly created connector must be registered by exynos_dsi.
The patch fixes exynos_drm on rinato and trats boards.

Fixes: 6afb7721 ("drm/exynos: move connector creation to attach callback")
