  avcodec/mpeg12dec: fix range for cc_format option
  
  After support was added for DVB 0502 Closed Caption coding,
  the cc_format option's range was never updated so user
  cannot select this coding as a forced formatting choice.
  
  Fix the range of the option by ending it with the new coding type.
