ipa: raspberrypi: imx296: Minor tuning updates
Some updates to the tuning for the imx296 sensors. For the colour variant: * Minor change to the AWB curve, making things a little less green. * Updated CCMs that reduce colour saturation to a more accurate level. Thanks to Dr. Rolf Henkel for these measurements and calculations. * Sharpening has been toned down quite a lot. * rpi.focus algorithm added so that the focus measure can be accessed. The sharpening and focus changes are applied to the mono version of the sensor too as we expect similar characteristics.
