[PATCH v4 10/11] libcamera: simple: Require metadata only when software ISP is used

[Milan Zamazal]

If software ISP is enabled then metadata is required in the simple
pipeline.  But this doesn't apply if the software ISP is not actually
used, for example when only a raw stream is produced.  Then the pipeline
waits for metadata that never comes.

This patch fixes the problem by requiring metadata only when software
ISP is used.
