ipa: raspberrypi: imx477: Update tuning file for the latest camera modules
The latest camera modules have a very slightly different IR filter, so the tuning file is slightly revised to give best results with both old and new camera modules. The original tuning file is retained as imx477_v1.json in case anyone should wish to continue using it.
