uapi: raspberrypi: Update the bcm2835-isp header definition

Browse source 
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.
