dp: look at all sinks and sources in default "is ready"

[marcinszkudlinski]

The default "is ready to process" implementation used to look at a first sink and first source only.

This change makes it to look at all sinks and sources.

dependency:

• module: Add support for saving and retrieving the base config extension #8575
  OR
• Better handling of module base_config_ext data #8685

Ready to go, just waiting for the dependency to be merged.

@marcinszkudlinski do we need to update the dependencies given we have new PRs from @andyross ?

[andyross]

@lgirdwood I have this patch in my "all my AEC junk" integration branch at https://github.com/andyross/sof/tree/mtl-aec-on-main and it's working great on MTL for me. There are only three cherry picks from mtl-007-drop-stable needed for working audio at this point[1], the other two being pipeline-related.

[1] Though there are about a dozen power/clock management patches in there to both SOF and Zephyr that have skewed vs. what merged upstream. That will probably take some work to untangle.

Forgot +1

@lgirdwood it is independent - just need one of the PRs above merged

One fail https://sof-ci.01.org/sofpr/PR8668/build1397/devicetest/index.html?model=TGLU_RVP_NOCODEC-ipc4&testcase=check-suspend-resume-with-playback but that's a new problem in baseline #8721
