dm: video: Add a operation to display uclass
The current display class only allow to get timing from edid. So add a operation to get timing directly from driver. In driver, I will use fdtdec_decode_display_timing to get timing. Signed-off-by: Jacob Chen <jacob-chen@iotwrt.com> Acked-by: Simon Glass <sjg@chromium.org>
