[PATCH v4 17/20] pipeline: rkisp1: make RkISP1CameraConfiguration a friend of the pipeline handler

[Stefan Klug]

For the validate() implementation, the RkISP1CameraConfiguration needs
access to dewarper related members of the PipelineHandlerRkISP1 object.
Allow this access by adding const versions of the pipe accessors and
making RkISP1CameraConfiguration a friend of PipelineHandlerRkISP1.
