net/mlx5: Register devlink ports for satellite PFs

Browse Source 
Include satellite PFs in mlx5_eswitch_is_pf_vf_vport() so they receive
the standard PF/VF devlink port operations. Update
mlx5_esw_devlink_port_supported() and devlink port attribute setup to
register SPF devlink ports with controller number and PF number.

Add mlx5_esw_spf_vport_to_idx() to look up the SPF array index by vport
number, and mlx5_esw_is_spf_vport() boolean wrapper to identify
satellite PF vports.
