This register allows swapping bytes, which can be used to implement UYVY from YUYV. Add a feature flag to signify the presence of this feature, and add it to the i.MX8MP match data. Also add it as a flag to the format info in the list of supported formats by the capture v4l2 devices, and update enum_fmt and s_fmt to take it into account.
