V4L/DVB: Rework for support xc5000

Set correct GPIO number for BEHOLD_WANDER/VOYAGER
Add xc5000 callback function
Small rework tm6000_cards_setup function
Small rework tm6000_config_tuner, build mode_mask by config information
Rework for support xc5000 silicon tuner
Add some information messages for more better understand an errors.
