It's not clear why this should be needed.  Don't function drivers 
already allocate endpoints amongst themselves as part of configuration 
initialization?  After all, we can't have two different interfaces 
trying to use the same endpoint.

If this is a matter of figuring out which function driver owns an
endpoint, can't that be done by searching through the endpoint
descriptors for each function's active interfaces?
