Introduce v4l2-isp.h in the Linux kernel uAPI. The header includes types for generic ISP configuration parameters and will be extended in the future with support for generic ISP statistics formats. Generic ISP parameters support is provided by introducing two new types that represent an extensible and versioned buffer of ISP configuration parameters. The v4l2_params_buffer represents the container for the ISP configuration data block. The generic type is defined with a 0-sized data member that the ISP driver implementations shall properly size according to their capabilities. The v4l2_params_block_header structure represents the header to be prepend to each ISP configuration block.
