The series targets fixing and improving maximum resolutions that can be
streamed on the pipeline, successfully.

1/2 targets fixing the issue where the RkISP1MainPath was considering max
supported size > ISP on i.MX8MP.

2/2 filters out sensor sizes that cannot be supported by the pipeline.
Such sizes are filtered out and the highest resolution (supported by
sensor) is considered as the max sensor resolution for
generateConfiguration() and validate() code paths.

https://patchwork.libcamera.org/patch/19411/

Based on series:
libcamera: rkisp1: Plumb the dw100 dewarper as V4L2M2M converter v7

Changes in v2:
- Use const for variables in 1/2
- Add comment on why we need to bound max size 1/2
- Use std::map<> in 2/2 for sensor sizes as multiple
  sensor can be attached to same ISP.
