If there are no more comments I would like to apply this to dm/master
and enable driver model in SPL. I think that putting #ifdef around
gdata instead of removing it is safer for now. We can always remove it
later.

However if we are going to Masahiro's 'single .config' series soon (as
I hope!) then I will hold off, and rebase against that once it is
applied.
