drm/armada: Remove armada_drm_debugfs_cleanup()
drm_debugfs_cleanup() now removes all minor->debugfs_list entries
automatically, so no need to do this explicitly. Additionally it
uses debugfs_remove_recursive() to clean up the debugfs files,
so no need for adding fake drm_info_node entries.
And finally there's no need to clean up on error,
drm_debugfs_cleanup() is called in the error path.
