I didn't see the ranges from the tuner, because the dvb-c drivers don't use the pll framework. They
have very simple tuning functions only. We should use both values. One part may be more restrictive
than the other one.

The intention to write the frequency patch was some trouble with w_scan, which starts on 50.5MHz.
