====================
devlink: linecard and reporters locking cleanup

This patchset does not change functionality.

Patches 1-2 remove linecards lock and reference counting, converting
them to be protected by devlink instance lock as the rest of
the objects.

Patches 3-4 fix the mlx5 auxiliary device devlink locking scheme whis is
needed for proper reporters lock conversion done in the following
patches.

Patches 5-8 remove reporters locks and reference counting, converting
them to be protected by devlink instance lock as the rest of
the objects.

Patches 9 and 10 convert linecards and reporters dumpit callbacks to
recently introduced devlink_nl_instance_iter_dump() infra.

Patch 11 removes no longer needed devlink_dump_for_each_instance_get()
helper.

The last patch adds assertion to devl_is_registered() as dependency on
other locks is removed.
