video: theadorable: Use RGB565 for BMP blitting
At present this uses RGB555 format for blitting to a display. Sandbox uses 565 and that seems to be more normal for BMP as well. Update the code accordingly and add a test. Note that this likely breaks the theadorable board so we may need to discuss supporting both formats. Signed-off-by: Simon Glass <sjg@chromium.org>
