pipeline: simple: Update documentation on pipeline setup

After commit 4671911df040 ("pipeline: simple: Use breadth-first search to setup media pipeline"), the explanation in the SimplePipeline documentation how the handler tries to find a valid path to capture device does not reflect the reality anymore. Update the text to the new situation.
