Clean-up adsp-main-6.12 series

[pamolloy]

This base series is a refactored version of the current adsp-main-6.12 branch. The minimal diff with adsp-main-6.12 is below. Note this is getting merged into a new branch, adsp-6.12.0-y.

I will then apply a set of fixup commits in an attempt to pass CI/CD. Only the fixup commits need to be reviewed.

Once merged adsp-main-6.12 can be replaced. And then this series can be manually rebased on top of adsp-main-6.12.38-y, which contains Artur's series that is being mainlined.
