thinking about this series in the context of some other patches I've been
reviewing recently, I don't think this series should be talking about
supporting multiple radios with a single wiphy, but instead about supporting
multiple devices with a single wiphy. After all, the existing logic already
supports a single device with multiple radios, so it isn't the multitude of
radios that is the issue, it is the multitude of devices.

this would have ramifications on many of the commit messages in this series.
