This register allows swapping bytes, which can be used to implement UYVY from YUYV. Add a flag to the format info in the list of formats supported by the capture v4l2 devices, and update enum_fmt and s_fmt to take it into account. To signify the presence of this feature, reuse the MAIN_STRIDE feature flag, as it is very likely that any ISP version that supports one of these two features will also support the other.
