devlink: expose nested devlink for a line card object
If line card object contains a nested devlink, expose it.
Example:
$ devlink lc show pci/0000:01:00.0 lc 1
pci/0000:01:00.0:
lc 1 state active type 16x100G nested_devlink auxiliary/mlxsw_core.lc.0
supported_types:
16x100G
$ devlink dev show auxiliary/mlxsw_core.lc.0
auxiliary/mlxsw_core.lc.0
