media: rppx1: ccor: Add support for color correction matrix
Extend the RPPX1 driver to allow setting the color correction matrix
configuration parameters. It uses the RPPX1 framework for parameters and
its writer abstraction to allow the user to control how, and when,
configuration is applied to the RPPX1.
