There isn't an ioctl to enum the supported field orders, so a user-space
application can call VIDIOC_TRY_FMT using different field orders to know
if one is supported. For example, GStreamer does this so during playback
dozens of the following messages appear in the kernel log buffer:
[ 442.143393] Not supported field order(4)
Instead of printing this as an error, just keep it as debug information.
