75548c8bf3 tuner_fc0013: improve tuning resolution 
We now use Hz instead of kHz for the internal
calculations, and thus improve the tuning resolution
to ~50 Hz (tested with DAB).

589e96e8d8 Using a #define for constant 2^22 (not pow()) 
pow() might require the math library to be linked with
rtl-sdl (e.g. when compiling with clang), even though
it's actually constant.

bad6fb080b 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
