ipa: raspberrypi: Add support for the Sony IMX708 sensor
Add support for Raspberry Pi Camera 3 modules (Sony IMX708 camera sensor) to the Raspberry Pi IPA. These modules are available in either normal or wide angle lens, both with IR or no IR cut options, giving a total for 4 variants. Provide IQ tuning files for all four variants. The IMX708 camera helper additionally parses PDAF and HDR histogram data that is provided in the embedded data stream from Unicam.
