Regardless of what we do with the Cirrus DSP this just seems like a good
idea - surprises due to this not being generally available keep coming
up, IIRC with the i.MX firmware in the past for example.

We could also merge a tag into both places.

Trying to enforce distinctions here feels like it's liable to lead to
trouble at some point...
