apply frequency correction value on the xtal clock directly
...
by using this approach both, the tuning frequency and the sample rate
should be corrected at the same time.

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).

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.
