devlink: print controller prefix for non-zero controller ...
The controller prefix (c<N>) in phys_port_name is currently restricted
to external host controllers. This layout sufficed when DPUs only had a
single local controller and one or more external host controllers.
However, newer devices can have multiple controllers within the DPU
itself, even within a single host environment. To support these
topologies, allow drivers to report the controller number regardless of
the "external" flag status. Any non-zero controller number will now be
explicitly reported, even for single-host or local DPU controllers.
Existing ports with controller=0 are unaffected.
Update documentation and kdoc to clarify that a non-zero controller
number does not require the external flag to be set.
