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.

Remove use of vcsm allocations and replace with dma heap allocations.
The pipeline handler now passes the fd of the allocation over to the IPA
instead of the raw pointer.
Also use libcamera::FileDescriptor for fd lifetime management.
This commit must be built alongside the accompanying BCM2835 ISP kernel
driver changes at https://github.com/raspberrypi/linux/pull/3715.
Otherwise a mismatch will cause undefined behavior.

This commit adds the headers and definitions required for the
bcm2835_isp and bcm2835_unicam kernel modules.
The headers come from patches recently posted to the
linux-media@vger.kernel.org mailing list to add the Unicam and ISP
peripherals drivers to the kernel.
