Add a new function to activate an existing simple frame buffer node and add the associated reserved memory, with no-map properties. This device tree update is only done when the video device is active and the video buffer is used. This patch uses '#if CONFIG_IS_ENABLED(DM_VIDEO)' because gd->video_bottom and gd->video_top are only defined when CONFIG_DM_VIDEO is activated.
