Stefan Agner b7868c68a5 drm/fsl-dcu: use drm_mode_config_cleanup on initialization errors
Commit 7566e24767 ("drm/fsl-dcu: handle initialization errors properly")
introduced error handling during initialization, but with a wrong cleanup
order.

Replace the error handling with the generic cleanup function
drm_mode_config_cleanup.
