libcamera: pipeline: rkisp1: Setup links as part of configuration
In preparation of supporting both the main and self path configure all the media graph links as a part of the configuration step. Before this change the link between ISP and DMA engine was setup at match time as the only supported path was the main path and only the link between sensor and ISP was updated at part of the configuration step. The main path is still the only path between ISP and DMA engine that is possible to enable.
