libcamera: ship the IMX896 colour tuning (r6)
Some checks failed
image / image (push) Failing after 4m4s
Details

Browse source 
Adds imx896.yaml (CCMs for 2800/4000/5750 K) so the main camera gets
real colour instead of the uncalibrated fallback. The matrices are
numeric calibration data read out of the stock Android tuning blob -
measured spectral response of this sensor, not authored expression -
and are shipped by the project owner's decision, consistent with the
vendor-derived data this image already carries. Durable replacement is
to measure our own from a colour chart.

Note the file lists Adjust/Agc/Af as well as BlackLevel/Awb/Ccm: a
sensor-specific tuning file REPLACES the fallback's algorithm list, so
omitting them silently disables auto-exposure and autofocus.
