I don't have a problem adding support for testing that property and
skipping most of the initial HW setup, basically treating the endpoint
as pre-configured.

What about using a value for "status" ? Or an empty "configured"
property ? Ideally, it should have been the other way around, ie
"unconfigured" for old/buggy stuff but I'm worried there may be existing
out-of-tree device-trees without it :-)
