The OF specs do not specify how to process a config type ranges entry,
and we all mutually agreed that the only sane interpretation for such
a thing would be to describe an ECAM memory space so generic code
could potentially make use of it.

Since designware is not ECAM it should not use config ranges.

This has come up multiple times now, and the above is the consensus.
