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

The driver was taken from http://git.linuxtv.org/ and adapted
for librtlsdr. Also, fc0013_set_gain() was added.

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
