pipeline: rkisp1: Support raw Bayer capture at runtime
Implement support for raw Bayer capture at runtime, from start() to
stop(). Support of raw formats in the camera configuration is split to a
subsequent change to ease review.
In raw mode, the ISP is bypassed. There is no need to provide parameter
buffers, and the ISP will not generate statistics. This requires
multiple changes in the buffer handling:
- The params and stats buffers don't need to be allocated, and the
corresponding video nodes don't need to be started or stopped.
- The IPA module fillParamsBuffer() operation must not be called in
queueRequestDevice(). As a result, the IPA module thus doesn't emit
the paramsBufferReady signal. The main and self path video buffers
must thus be queued directly in queueRequestDevice().
- The tryCompleteRequest() function must not to wait until the params
buffer has been dequeued.
- When the frame buffer has been captured, the IPA module
processStatsBuffer() operation must be called directly to fill request
metadata.
