media: dvb: represent min/max/step/tolerance freqs in Hz
Right now, satellite frontend drivers specify frequencies in kHz,
while terrestrial/cable ones specify in Hz. That's confusing
for developers.
However, the main problem is that universal frontends 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 frontends.
So, convert everything to specify frontend frequencies in Hz.
