4.19-stable review patch. If anyone has any objections, please let me know.

From: Mauro Carvalho Chehab mchehab+samsung@kernel.org
commit 3d8e450f517cdb33da77827ec75929354753e9c0 upstream.
Tuners should report frequencies in Hz. That works fine on most drivers, but, in the case of dvb-pll, some settings are for satellite tuners, while others are for terrestrial/cable ones.
The code was trying to solve it at probing time, but that doesn't work, as, when _attach is called, the delivery system may be wrong.
Fix it by ensuring that all frequencies are in Hz at the per-tuner max/min values.
While here, add a debug message, as this would help to debug any issues there.
It partially fixes the following bug: https://bugzilla.opensuse.org/show_bug.cgi?id=1116374
