[media] tm6000: fix s-video input

Add compatibility for composite and s-video inputs. Some TV cards hasn't
it.

Fix S-Video input, the s-video cable has only video signals no
audio. Call the function of audio configure kill chroma in signal. only
b/w video.

Known bugs:
  - after s-video the audio for radio didn't work, TV crashed hardly
  - after composite TV crashed hardly too.

P.S. After this patch I'll want to rework the procedure of configure
     video. Now it has a lot of junk and dubles.

With my best regards, Dmitry.
