It is a long time since i converted an ARM system from platform data
to DT. But what we tended to do was to allow both for a period of
time.

Does a system using platform data still work after this change? The
first patch seems to delete a lot of code, not just move it around.

Can you restructure this patchset to add the glue layer and DT binding
in parallel with platform data. Then have a patchset which convert all
in tree machines to using DT. And then a patchset, submitted in maybe
6 months time, to remove support for platform data.
