Two tuning files for the two cameras of the Surface Pro 8, the ov13858 at the
back and the ov5693 in front. Both already work with the software ISP, but
with no tuning file they fall back to uncalibrated.yaml and the colour is
visibly green.

This follows the September thread where Kieran said per-sensor tuning is
wanted, and that the licensing of matrices read out of a vendor blob is not
settled. The gains and matrices here come from the AIQB that ships with the
Windows driver of this machine; the black level is measured. The provenance
is stated in the commit message rather than the numbers being presented as
mine, so the decision stays with the maintainers.

One question this series runs into: the tuning file is looked up by sensor
model, and the ov13858 is also the rear camera of the Surface Pro 11, where
Sergey has a file from a different module. Two modules, one name. Do you
want a per-module scheme, and if so what should the file be called, or
should one module be picked as representative for the sensor?
