With the introduction of v4l2-isp.h in the Linux kernel currently in
progress:
https://lore.kernel.org/all/20250915-extensible-parameters-validation-v5-0-e6db94468af3@ideasonboard.com/

the MaliC55 ISP driver at version in v11 has been ported to use a
parameters format compatible with the one defined by v4l2 extensible
parameters:
https://lore.kernel.org/all/20250714-c55-v11-0-bc20e460e42a@ideasonboard.com/

This series
1) Imports v4l2-isp in libcamera
2) Update the Mali C55 header and IPA to compile with v11 of the patch
   series that introduces MaliC55 support in Linux
3) Introduces V4L2Params by generalizing RkISP1Params
4) Ports the Mali C55 IPA to use the newly introduced V4L2Params

Tested on rkisp1 and rzv2h
