Convert the existing data struct to use the QAM modulation macros,
instead of assuming that they're numbered from 0 to 5.

If the i2c write fails during initialisation, an oops happens
because state->frontend.dvb is still undefined. Fixed.

Thanks to Sigmund Augdal for reporting this bug,
and to Hartmut Birr for suggesting the fix.

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.

Remove incorrect range check of symbol rate, spotted by the coverity 
checker and reported by Adrian Bunk.

These range checks are performed by dvb_core now.
