libcamera: pipeline: rkisp1: Move path configuration generation and validation to RkISP1Path
Move the path configuration generation and validation to RkISP1Path. This is done to increase code reuse and to encapsulate the main and self path differences inside the RkISP1Path class. There is no functional change. Signed-off-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
