introduce api to configure crystal oscillator frequency

Usually both, the RTL and the tuner ICs use the same clock. Changing the
clock may make sense if you are applying an external clock to the tuner
or to compensate the frequency (and samplerate) error caused by the
original cheap crystal.

This commit covers all tuner drivers except of the Fitipower FC2580
