v4l2: v4l2_camera_proxy: Use stream config in tryFormat
For handling try_fmt, the values should be filled in by validating the stream configuration, and not by recalculating them or manually checking against the cached list of formats and sizes. Add a new V4L2Camera::validateConfiguration() function to validate a configuration and use it to obtain size, format, stride, and frameSize values. If the format negotiation fails, return error from try_fmt and s_fmt. Signed-off-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
