[PATCH v6 0/2] ipa: rkisp1: Improve AGC (plumbing)

[Paul Elder]

This series adds support in the rkisp1 IPA for:
- reading histogram weights (metering modes) from tuning file
- plumbs controls for setting metering mode, exposure mode, constraint
  mode, and frame duration

As of v2, defaults have been added such that the rkisp1 pipeline will no
longer break with non-existent/erroneous tuning files.

v3 mainly adds support for both v10 and v12, and fixes a limits issue in
when using the exposure mode helper.

v4 only has minor changes.

v5 only changes PointF to the typedefed version from Vector (see the
dependent series for details).

v6 removes the piecewise linear function-ization of the luminance
target, and some more cleanups.
