net/mlx5: Set satellite PF devlink ports as non-external

Browse Source 
Satellite PFs are local to the DPU and are not on an external host.
Set their devlink port external attribute to false to reflect this.

For satellite PF SFs, distinguish them from host PF SFs by comparing
the SF controller number against the host PF controller
(hpf_host_number + 1). Only SFs whose controller matches the host PF
are marked external, since their PF resides on an external host.
