RDMA/mlx5: Support plane device and driver APIs to add and delete it
This patch supports driver APIs "add_sub_dev" and "del_sub_dev", to
add and delete a plane device respectively.
A mlx5 plane device is a rdma SMI device; It provides the SMI capability
through user MAD for it's parent, the logical multi-plane aggregated
device. For a plane port:
- It supports QP0 only;
- When adding a plane device, all plane ports are added;
- For some commands like mad_ifc, both plane_index and native portnum
is needed;
- When querying or modifying a plane port context, the native portnum
must be used, as the query/modify_hca_vport_context command doesn't
support plane port.
