media: imx: capture: refactor enum_/try_fmt
By checking and handling the internal IPU formats (ARGB or AYUV) first,
we don't need to check whether it's a bayer format, as we can default to
passing the input format on in all other cases.
This simplifies handling the different configurations for RGB565 between
parallel and MIPI CSI-2, as we don't need to check the details of the
format anymore.
