media: ngene: use defines to identify the demod_type

Browse source 
Make it more clear which demod_type is used for which hardware by having
defines for the possible demod_type values. With that, change the
demod_type evaluation in tuner_attach_probe() to a switch-case instead
of an if() for each possible value.
