FWIW these seem to have moved about. I couldn't find stuff in the
upstream Linux tree but in the raspbian kernel tree there is stuff in:

  include/linux/platform_data

but I couldn't find the exact place for these definitions. However I
wouldn't worry too much if they did come from a distributed kernel they
should be GPLv2.
