I think the support for legacy platform_data should be left out
of this patch. I am working on a series that removes unused
platform_data headers for machines that have DT support and no
longer use static platform_device declarations anywhere in
the kernel, so if you add another instance, that would just
get removed again in the near future.

Just don't add it here. If there are users that use traditional
boardfiles instead of DT, they already need kernel patches to
add the board files, and adding in the driver support can be
part of the same patches.
