From: Simon Glass <sjg@chromium.org> Add a way to tell the console that the machine is idle. This will be used (later) to show the cursor. Call the video console sync after that, so that any updates are shown. Keep the video_sync_all() for the case where CONFIG_CURSOR is not enabled, to reduce code size.
