From: Nicholas Roth <nicholas at rothemail.net>
Currently, libcamera does not have information for the ov8858 sensor
used in the PinePhone Pro, a phone designed to run Linux.
This commit adds metadata, especially that sensor gain is reported and
set in 1/16 discrete increments.
For more information, see "5.8 manual exposure compensation/ manual
gain compensation" in [0] and the driver in [1].
