On the path towards a cleaner and more documented IPA for the IPU3, this
series changes the structures used by the AWB algorithm.
This v4 changes the way the structure is used in intel-ipu3.h to avoid
any change in the buffer size. It should be transparent.

Patch 1/4 moves the AWB structures to be able to use those from the
ipa::ipu3::algorithms namespace (by AGC at least).

Patch 2/4 renames the stats region structure to make it clear it is an
accumulator structure.

Patch 3/4 is improving the Accumulator structure to have the same layout
as the IPAFrameContext::awb structure.

Patch 4/4 is removing the IPU3AwbCell from libcamera, and uses its
definition directly from the kernel header. 


Jean-Michel Hautbois (4):
  ipa: ipu3: Move the AWB stats structures
  ipa: ipu3: Rename IspStatsRegion to Accumulator
  ipa: ipu3: Change Accumulator structure layout
  ipa: ipu3: Replace ipa::ipu3::algorithms::Ipu3AwbCell
