libcamera: src: ipa: raspberrypi: agc: Improve gain update calculation for partly saturated images
When parts of an image saturate then the image brightness no longer
increases linearly with increased exposure/gain. Having calculated a
linear gain value it's better then to try it, allowing for saturating
regions, and if necessary increase the gain some more. We repeat this
several times.
