This patch series adds the crosstalk / color correction algorithm to
the rkisp1 IPA.
The last patch in this series depends on "[PATCH] libcamera: utils: Add
a helper to convert floating-point to fixed-point".
Interpolating matrices is likely to be a common functionaily, as lens
shading correction also does it, and other IPAs will will want to do
both color correction and lens shading correction. Because of this, the
crosstalk is implemented using a generic matrix interpolator, which is
added to libipa, in addition to a Matrix class.
v3 mainly adds ccm offsets, and some fixes some initialization and
asserts.
