Implement a dummy DVB tuner as part of ongoing work
on a virtual DVB test driver under the 2020 Spring Linux
Kernel Mentorship Program.
The virtual DVB test driver serves as a reference DVB driver and helps
validate the existing APIs in the media subsystem. It can also aid developers
working on userspace applications.
This dummy tuner should support common TV standards such as DVB-T/T2/S/S2,
ISDB-T and ATSC when completed.
For now, only a basic skeleton is available, most functions do nothing
whatsoever.
