drm/exynos: fix drm driver de-initialization order 



Since components have their own cleanup routines calling
drm_mode_config_cleanup before component_unbind_all causes errors
due to double free of KMS objects. The patch fixes it by changing
de-initialization order. Now it is exactly opposite to init order.
