[PATCH v6 06/13] drm/sun4i: add a dedicated module for sun4i-backend and sun4i-layer

Currently the direct call from CRTC code to layer code has disappeared,
instead the layer's init function is called via the backend's ops.

Add a dedicated module for sun4i-backend and sun4i-layer, and drop the
EXPORT_SYMBOL from backend code to layer code.
