Those are the tuners supported by the tuner_core logic. The tuner_core module
is required by all TV drivers that have analog support.

After the tuner rework to allow a driver under drivers/media/dvb to use the
same tuner module as the ../v4l modules, there are now pure dvb drivers that
don't use tune_core.

So, it makes sense to add a new config for tuner_core that will be
selected only for devices with analog TV support.

Mauro
