Subject: [PATCH v2 6/6] drm/todo: update the debugfs clean up task

The structs drm_debugfs_info and drm_debugfs_entry introduced a new
debugfs structure to DRM, centered on drm_device instead of drm_minor.
Therefore, remove the tasks related to create a new device-centered
debugfs structure and add a new task to replace the use of
drm_debugfs_create_files() for the use of drm_debugfs_add_file() and
drm_debugfs_add_files().
