RDMA/core: Support IB sub device with type "SMI"
This patch adds 2 APIs, as well as driver operations to support adding
and deleting an IB sub device, which provides part of functionalities
of it's parent.
A sub device has a type; for a sub device with type "SMI", it provides
the smi capability through umad for its parent, meaning uverb is not
supported.
A sub device cannot live without a parent. So when a parent is
released, all it's sub devices are released as well.
