drm/fb-helper: Disable cursors and planes when restoring fbdev mode
Cursors and plane can obscure whatever fbdev wants to show the user.
Disable them all in drm_fb_helper_restore_fbdev_mode.
After the cursors and planes have been disabled, user space needs to
explicitly re-enable them to make them visible again.
