[media] cx231xx: Add initial support for Hauppauge USB-Live2

Add initial support for the Hauppauge USBLive 2 (2040:c200).  Note that I
had to copy a bunch of the case statements used for the Conexant video grabber
reference design (which also doesn't have a tuner).  This will likely need to
be refactored out into the board profile.
