pipeline: rkisp1: make RkISP1CameraConfiguration a friend of the pipeline handler

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.
