Sounds good. Even if Nicolas thinks there may be users of the
SPI interface with the existing DT binding, we can still decide
to remove the MMIO interface entirely, as I first suggested.

Apparently the chips are still in production and are commonly
used with microcontrollers, but the only reference I found
about using Linux with it is in a blog post that mentions
an "official" driver from the manufacturer, with an
(incompatible) compatible="w5000-wiz0" DT binding:
