net/mlx5: Consolidate devlink documentation in devlink/mlx5.rst

De-duplicate documentation by removing mellanox/mlx5/devlink.rst. Instead,
only use the generic devlink documentation directory to document mlx5
devlink parameters. Avoid providing general devlink tool usage information
in mlx5-specific documentation.
