    V4L/DVB (6783): tuner: combine set_tv_freq and set_radio_freq into a single 
set_params method
    
    We can tell whether we are tuning television or radio by testing for
    struct analog_parameters *params->mode == V4L2_TUNER_RADIO
    
    There is no longer any need for separate set_tv_freq and
    set_radio_freq functions in the analog tuner demodulator modules.
