Leon Romanovsky 8b92a2c930 rdma: Move per-device handler function to generic code 
Most of the proposed objects are working in the scope "dev"
and will implement the same logic. Move the code to utils.c,
so other objects will be able to reuse the code.

Leon Romanovsky 74bd75c2b6 rdma: Add basic infrastructure for RDMA tool 
RDMA devices are cross-functional devices from one side,
but very tailored for the specific markets from another.

Such diversity caused to spread of RDMA related configuration
across various tools, e.g. devlink, ip, ethtool, ib specific and
vendor specific solutions.

This patch adds ability to fill device and port information
by reading RDMA netlink.
