This patch series adds the crosstalk / color correction algorithm to
the rkisp1 IPA.

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.

v2 mainly upgrades the Matrix class to use template arguments for size,
and renames ctk to ccm.
