Subject: [PATCH] temp/libcamera: Apply s5kjn1 CCM tuning to imx376 as well

It's far from perfect but better than the default. Most importantly it
gives users of the OP6 - one of the most popular devices - an impression of
where libcamera development is heading - and an incentive to help/play
around with tuning.
