drm/debugfs: create device-centered debugfs functions
Introduce the ability to track requests for the addition of DRM debugfs
files at any time and have them added all at once during
drm_dev_register().
Drivers can add DRM debugfs files to a device-managed list and, during
drm_dev_register(), all added files will be created at once.
Now, the drivers can use the functions drm_debugfs_add_file() and
drm_debugfs_add_files() to create DRM debugfs files instead of using the
drm_debugfs_create_files() function.
