Ugh, this is just leading to horrible code here (and why on earth aren't
we just implementing fixups for DT data?).  Though that said I don't
understand why the code here isn't just checking that there's platform
data rather than setting a flag that says there's platform data, the
driver already needs to use the presence of platform data as a check
anyway.
