    V4L/DVB (5985): Fix the min/max frequencies of some DVB-C frontends
    
    The min frequencies of the DVB-C frontends are wrong.
    
    In Europe, the center frequency of the lowest channel is 50.5MHz and not
    51MHz. All known cards with the stv0297/tda0002x/ves1820 frontend are
    able to tune to this frequency.
    
    I've changed the range to the lowest channel - 1/2 bandwidth and the
    highest channel + 1/2 bandwidth. For the design of the dvb driver, the
    frequency ranges must be part of the tuner and not of the frontend
    itself. The same frontend may be used for different tuners.
    
    The attached patch does only fix the ranges and not the design.
