[PATCH 4/7] state: support deep probe

[Ahmad Fatoum]

With deep probe, drivers registered before of_populate_initcall must
themselves take care to ensure their dependencies had a chance to probe.

For barebox-state, this means the backend partition provider must be
probed. Do so by calling of_partition_ensure_probed on it.
