We _really_ need some way to support more than one board per binary
before we can move everything to DM only.

I think we can kind of do this today if we stick to using platform data
for everything that's board-specific rather than SoC-defined.  What we
talked about at ELCE was auto-generating the pdata from the device tree,
I think.
