The individual messages mostly speak for themselves.

It is very possible that there are more chips out there that are
impacted by this, but I only have access to the errata document for
the T1024 family, so I've limited the DT changes to the exact FMan
version used in that device. Hopefully someone from NXP can supply a
follow-up if need be.

The final commit is an unrelated fix that was brought to my attention
by sparse.
