Subject: [PATCH mlx5-next v1 4/5] IB/mlx5: Limit the scope of struct mlx5_bfreg_info to mlx5_ib

From: Leon Romanovsky <leonro@...lanox.com>

struct mlx5_bfreg_info is used by mlx5_ib only but is exposed to both
RDMA and netdev parts of mlx5 driver. Move that struct to mlx5_ib
namespace, clean vertical space alignment and convert lib_uar_4k
from bool to bitfield.
