I don't understand why a device that has a fwnode would ever be a "faux"
device?  Why wouldn't that just be a normal platform device?

faux devices were created to be not platform devices, to take away the
abuse where platform devices were being used because the api was simple
and people wanted a device in the tree somewhere, but there was not
actually any backing platform device present.

So the use of a fwnode here feels very odd to me, what am I missing?
