I think we really should just drop _prep_type from being exported.  the
uc* stuff doesn't look to be used, but we can clean that up as its
converted to arch/powerpc.  But I don't think anything out of tree uses
_prep_type (it's used at a very low level, it really couldn't be used at
the modular level).
