[PATCH v1 4/6] media: rkisp1-isp: Propagate sink -> source format in YUV passthough

[Isaac Scott]

If we are in bypass mode, we should propagate the sink format of the ISP
to the source format to ensure the pipeline is valid. Ensure the source
pad format of the ISP is configured to the same format as the sink pad.
