The current interconnect provider interface is inherently racy as providers are expected to be added before being fully initialised.
Specifically, nodes are currently not added and the provider data is not initialised until after registering the provider which can cause racing DT lookups to fail.
Add a new provider API which will be used to fix up the interconnect drivers.
The old API is reimplemented using the new interface and will be removed once all drivers have been fixed.
