net/mlx5: Suspend auxiliary devices only in case of PCI device suspend

net/mlx5: Suspend auxiliary devices only in case of PCI device suspend

[ Upstream commit 72ed5d5624af384eaf74d84915810d54486a75e2 ]

The original behavior introduced by commit c6acd629eec7 ("net/mlx5e: Add
support for devlink-port in non-representors mode") correctly
re-instantiated uplink devlink port and related netdevice during devlink
reload. However with migration to auxiliary devices, this behaviour
changed.

Restore the original behaviour and tear down auxiliary devices
completely during devlink reload.
