Okay, here we go. These patches apply on top of the latest
af903x by Hans-Frieder Vogt. This adds support for the fc0011
tuner, which is used on a "cabstone" stick. (Its USB-id is already
in af903x's list).
I did some _very_ basic testing on this stuff and it basically seems to
work more or less.

Two patches for review and testing follow (inline for commenting and attached).
(Yes, the '#if 0' sections are going to be removed. I'm currently
testing on a 3.2 kernel, so I need them for now.)
