I'm sure you know how messy this is :(

We wanted to treat J7200 as a proper subset device of J721e but we
also know that didn't happen. These two SoCs ended up more different
than expected and although still very similar I believe continuing
to try to support both under one name is not the right solution.

We will split out J7200 from J721e in TF-A[0] for similar reasons,
might be time to do the same in u-boot.
