Subject: 2.6.39 "tuner-core: remove usage of DIGITAL_TV" breaks saa7134 with

    [media] tuner-core: remove usage of DIGITAL_TV
    
    tuner-core has no business to do with digital TV. So, don't use
    T_DIGITAL_TV on it, as it has no code to distinguish between
    them, and nobody fills T_DIGITAL_TV right.

This breaks my Pinnacle PCTV 300i DVB-T cards as they can no longer tune
DVB-T.

[  540.010030] tuner 3-0043: Tuner doesn't support mode 3. Putting tuner to sleep
[  540.011017] tuner 2-0043: Tuner doesn't support mode 3. Putting tuner to sleep
[  540.012012] tuner 3-0060: Tuner doesn't support mode 3. Putting tuner to sleep
[  540.013029] tuner 2-0060: Tuner doesn't support mode 3. Putting tuner to sleep

saa7134 needs to indicate digital TV tuning to mt20xx but it looks like
tuner-core no longer has any way to allow a tuner to indicate support
for this?

(mt2050_set_tv_freq in mt20xx.c uses V4L2_TUNER_DIGITAL_TV)
