Initial code from GATOS. This needs to be cleaned up, for example the bt829

code is practically untouched since xatitv (which was a standalone test
    program). However, it all worked and was debugged over long period of
    time, so I prefer to to mess with these for now.
New drivers: fi12xx (including MT2032 - this would be be split off later).
