drm/sun4i: layer: Assign backend pointer before calling DRM helpers 

We might want to use the backend pointer from DRM callbacks that get
called within drm_universal_plane_init(), such as the
.format_mod_supported callback.

Move the assignment of the layer's backend pointer to right after the
structure is allocated.
