Subject[PATCH 3/3] media: vidtv.rst: update it to better describe the frequencies
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.

part of its own initialization.
