V4L/DVB (10442): cx18: Fixes for enforcing when Encoder Raw VBI params can be set

Browse source

The Encoder will only allow the Raw VBI parameters, along with a number of
other API parameters, to take effect when no analog captures are in
progress.  These parameters must be set before the first analog capture starts,
be it MPEG, VBI, YUV, etc., and cannot be changed until the last one stops.  It
is not obvious to me what capture channel API parameters are shared and which
ones must be set per capture channel, so set them all for every analog
capture channel start up.  This fixes the driver so that VBI capture can be
started up after the MPEG capture is going.
