ipa: ipu3: Replace ipa::ipu3::algorithms::Ipu3AwbCell
The intel-ipu3.h public interface from the kernel does not define how to parse the statistics for a cell. This had to be identified by a process of reverse engineering, and later identifying the structures from [0] leading to our custom definition of struct Ipu3AwbCell. [0] https://chromium.googlesource.com/chromiumos/platform/arc-camera/+/refs/heads/master/hal/intel/include/ia_imaging/awb_public.h To improve the kernel interface, a proposal has been made to the linux-kernel [1] to incorporate the memory layout for each cell into the intel-ipu3 header directly. [1] https://lore.kernel.org/linux-media/20211005202019.253353-1-jeanmichel.hautbois@ideasonboard.com/ Update our local copy of the intel-ipu3.h to match the proposal and change the AGC and AWB algorithms to reference that structure directly, allowing us to remove the deprecated custom Ipu3AwbCell definition.
