====================
devlink: extend phys_port_name controller prefix to non-external ports

This series by Moshe includes the controller number in phys_port_name
for non-external ports with a non-zero controller, and updates the mlx5
driver to mark satellite PFs as non-external.

The controller prefix (c) in phys_port_name was previously only included
for ports marked as external. However, newer devices can have multiple
controllers within the DPU itself, even within a single host
environment. For example, a SmartNIC may have additional local PCI
physical functions that are managed by the eswitch but are not on an
external host. These ports use a non-zero controller number to
distinguish them from the eswitch manager's own functions, while the
external flag remains unset.

Patch 1 updates the devlink core to include the controller prefix in
phys_port_name for any non-zero controller, regardless of the external
flag. Documentation and kdoc are updated accordingly.

Patch 2 updates the mlx5 driver to set satellite PF devlink ports as
non-external, since they are local to the DPU. It also distinguishes
satellite PF SFs from host PF SFs when setting the external attribute.
