V4L/DVB (5438): Fix ivtv yuv threshold handling
Modifies automatic mode selection for yuv playback. Behaviour is now that
source video with a vertical resolution below that of the currently set
broadcast mode will be treated as progressive. Video with a vertical
resolution greater or equal to the current broadcast mode (up to 576 lines)
will be treated as interlaced.
