The code is broken because it doesn't work with DM and is going to be
removed due to lack of maintenance soon.  My problem with this series,
but I need to check that we can do what I want to do and still keep
travis green, is have this (and the other non-converted and thus
non-maintained drivers) depend on, not select BROKEN.

The Makefile warnings tell people the code is going to be removed and
I'm trying to have the window be:
1) LOUD warning about needing work
2) 1 release past those loud deadlines of the code there, but not built
unless you enable BROKEN (as yes, I see code that's not updated to use
DM as being broken)
3) Code removed.

All that said, I continue to be open to delaying conversion / removal if
we're having:
- A discussion and proposed patches to do the conversion, but people
  need more time.  The work is in progress, but people need time as it's
  not as easy to convert as hoped for various reasons.
- A problem converting the driver to DM as it's highlighting some other
  problem within DM or hitting a size constraint or other problem.
- Someone who is willing to do the DM work is just now seeing this.
  Yes, this is possible especially since our LOUD Makefile warnings are
  also easy enough to miss if you're just automating the build and not
  doing it manually.

But I am not fine with:
- Code that isn't converted AND
- Code that no one seems to be converting AND
- Code that no one says they are going to convert AND
- The conversion deadline has past.
