[PATCH] Make Compro VideoMate Vista T750F actually work

[Carlos Corbacho <carlos@strangeworlds.co.uk>]

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).

I've dropped remote control support for now - I need to re-review the original
patches in more detail and also differentiate between the T750 and T750F (I
know how to do this based on the eeprom, but that'll take some time to get
ready and getting the rest of the card working first is more important).
