Firmwares for encoders newer than MT8173 will include an ABI version
number in their initialization ack message. Add the capacity to manage
it and make initialization fail if the firmware ABI is of a version that
we don't support.
For MT8173, this ABI version field is reserved and thus undefined ; thus
ignore it on this chip. There should only be one firmware version available
for it anyway.

The virtual driver has now a minimal set of frequencies for a

Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
Satellite setups are different than terrestrial and cable ones,
as there is a device coupled at the antenna, called LNBf, which
converts the frequency from a GHz range at C-Band or Ku-Band
into an intermediate frequency at S-Band (ranging up to ~2GHz).
There are several different models of LNBf, with different
IF conversions, but the most common nowadays is called
Universal LNBf. Those got their frequency ranges extended in the
past, when Astra 19.2E sattellite was launched.
The universal LNBf has two local oscilators:
- 9.75 GHz
- 10.6 GHz
The first one is used when the frequency is between 10.7 GHz
up to 11.7 GHz. The second one is for frequencies between
11.7 GHz to 12.75 GHz.
With that, the IF signal will be at 950 MHz to 2,150 MHz range.
Add support for doing the above math, and make clear that
the frequencies expected by the driver should be at Ku-Band
range.

On real devices, signal strength is always a negative
number when represented in dBm. A more interesting
range is to use dBmV (which is what Kaffeine does,
for example). The conversion from the two units are
simple:
dBmV = dBm - 108
Usually, signal strength ranges up to 100dBmV. Adjust the
maximum value to be around 74 dBmV, when there's no
frequency shift, which represents a good signal.
With that, Kaffeine displays it a lot better.

so, it won't use any frequency table at all;
2) the code that checks for frequency shifts is called
at set_params. So, lock_status will never be zeroed;
3) the signal strength will also report a strong
signal, even if not tuned;
4) the logic is not excluding non-set frequencies.
