V4L/DVB (8648): ivtv: improve CC support
- change the work-queue to a single threaded high prio workqueue - use DMA instead of PIO for the sliced VBI data. - remove some incorrect tests - increase the internal VBI capture queue size for sliced VBI packets - ignore duplicate VBI lines With these changes it should finally be possible to get reliable closed captions.
