a3f90c75b8 media: dvb: convert tuner_info frequencies to Hz
Right now, satellite tuner drivers specify frequencies in kHz,
while terrestrial/cable ones specify in Hz. That's confusing
for developers.

However, the main problem is that universal tuners capable
of handling both satellite and non-satelite delivery systems
are appearing. We end by needing to hack the drivers in
order to support such hybrid tuners.

So, convert everything to specify tuner frequencies in Hz.

Plese notice that a similar patch is also needed for frontends.

675ee80163 [media] it913x: change driver model from i2c to platform
That tuner is integrated to demodulator and communicates via

99ca5557ff [media] it913x: rename its tuner driver to tuner_it913x
There are three drivers with *it913x name on it, and they all
belong to the same device:
	a tuner, at it913x.c;
	a frontend: it913x-fe.c;
	a bridge: it913x.c, renamed to dvb_usb_it913x by the
building system.

This is confusing. Even more confusing are the two .c files with
the same name under different directories, with different contents
and different functions. So, prepend the tuner one.

This also breaks the out-of-tree compilation system.
