V4L/DVB (7258): Support DVB-T tuning on the DViCO FusionHDTV DVB-T Pro

Add support for tuning DVB-T channels on DViCO's FusionHDTV DVB-T Pro board.

The IR remote and analog tuner are not supported at this time.

Some changes made by Mauro Chehab to allow merging it with some other xc3028
patches.
