line21dec: relax caps requirements

Instead of requiring interlaced video, simply skip CC detection
when the input is progressive.

This allows placing line21decoder unconditionally in pipelines,
without having to worry about whether the input stream will be
interlaced, or even worse interlacing just in case!

+ update doc cache
