Based on the work of John Newbigin, Davor Emard and others who contributed
on the mailing lists.

The previous 'support' for this card was a partial merge of John's changes
that, as far as I can tell, never actually got the thing working (no DVB-T,
analog tuner not initialised).

Initialise the analog tuner properly and hook up the DVB tuner and demodulator.

DVB-T and analog now work (though I can't tune every DVB channel, but I think
there's an issue with the aerial and signal boosters here that is causing
me problems).
