Do some spring cleaning:
- there are no board defines with tuners, so remove bogus tuner support.
- tv standard handling has nothing to do with tuners, so keep that.
- replace the deprecated current_norm by g_std.
- querystd isn't implemented, so remove the ioctl.
- remove a bunch of unused fields in cx25821.h

This device does not support radio or vbi, so remove anything referring
to that.
In addition, the driver created an 'video ioctl' node, which was unused and
was effectively identical to the first video node.
This bogus video node is now removed, leaving us with 8 video capture nodes
and 2 video output nodes.

The cx25821 driver has support for one audio output channel and two video
output channels.
This is implemented in a very ugly and very evil way through a custom ioctl
that passes the filename of a file containing the video data, which is then
read by the driver itself using vfs.
There are a number of problems with this:
1) it's very ugly and very evil (I can't say that often enough).
2) V4L2 supports video output, so why not use that?
3) it's very buggy, closing the filehandle through which you passed the ioctl
will oops the kernel.
4) it's a nasty security leak since this allows you to load any file in the
system as a video or audio source, so in theory you can output /etc/passwd
to audio or video out and record & decode it on another device.
Because of all these issues we no longer register those output video nodes.
