Given that we've converted stuff like MMCI to use DT, it _should_ be
the case that we can just add the appropriate DT description to the
existing Versatile DT - we might need to create some new GPIO devices
for things like SYSMCI and get rid of the status function, or we
could just use the auxdata stuff in the mean time.

Either way, we've solved these problems on other platforms, and the
shared code has already been fixed or is being fixed for stuff like
Versatile Express.

Lets also not forget that the VIC code has already been converted to
DT.

So I don't think there's a big problem here - I think most of the
pieces of the jigsaw are in place through converting other platforms.
