cba63cf8f9 [media] vivid: default to single planar device instances 
The default used to be that the first vivid device instance was
single planar, the second multi planar, the third single planar, etc.

However, that turned out to be unexpected and awkward. Change the
driver to always default to single planar.

62f28725a8 [media] vivid: add teletext support to VBI capture 
This is useful to test teletext capture applications like alevt and mtt.

It also fixes a previously undetected bug where the PAL VBI start line
of the second field was off by one. Using the new field start defines
helps a lot fixing such bugs.
