So, yes, we have not yet set a deadline on basic DM conversion.  I
haven't yet, and there's a few arches that haven't started and I'm
talking with privately to see where things stand there.

Yes, what to do when switching to platform data isn't enough is an open
question and I'm of a few minds still on if we should:
- Allow some drivers to retain non-DM for SPL-only.
- Declare that "TPL" is where the truly small and board/SoC/etc specific
  drivers need to reside.
- Something else.

As there's pros and cons to both of those approaches.
