Subject: [PATCH] schemas: Ensure -names properties' entries are unique

The common '.*-names' schema doesn't enforce that entries are unique as
there are a few oddballs. For all the normal cases, we need to enforce the
entries are unique by setting the type to "string-array".

Unfortunately, some oddball cases for 'dma-names' slipped in, so that one
can't be enforced.
