Subject[PATCH 3/3] media: vidtv.rst: update it to better describe the frequencies
Date
The virtual driver has now a minimal set of frequencies for a
single transponder to be found by each DVB standard.

Document it, and update related information about the
simulated LNBf.

That's it! The bridge driver will initialize the tuner and demod drivers as
part of its own initialization.
