uapi: raspberrypi: Update the bcm2835-isp header definition
Update the bcm2835-isp.h file with the latest version available in the downstream Raspberry Pi linux repo at commit: 68878170d8a98afd6d519a3a2c909080c19de4ce This change adds support for colour denoise processing, and the following downstream kernel changes must be available: https://github.com/raspberrypi/linux/pull/4069 https://github.com/raspberrypi/linux/pull/4083 The Raspberry Pi image must also be running the latest firmware, obtained by running rpi-update.
