drm/sun4i: Add missing drm_atomic_helper_shutdown at driver unbind

Browse source 
A call to drm_atomic_helper_shutdown is required to properly release
the internal references taken by the core and avoid warnings about
leaking objects. Add it since it was missing.

Fixes: 9026e0d122 ("drm: Add Allwinner A10 Display Engine support")
