RDMA/mlx5: Add new registration stage for data direct users
For the upcoming move of data direct to mlx5_core driver,
the API needs to be split into init and register stages.
That's because only the core will do the init phase but
both IB and netdev devices will need to register.
While data direct still lives in mlx5_ib, do all steps in
mlx5_ib_data_direct_init().
While at it, make mlx5_data_direct_query_vuid() private
as it is no longer needed.
This patch has no functional changes. It is a preparation
for moving data direct infrastructure to mlx5_core. For
this reason the new functions are added to the new header.
