mlxsw: spectrum_ethtool: Add link extended state

Browse source

Implement .get_down_ext_state() as part of ethtool_ops.
Query link down reason from PDDR register and convert it to ethtool
link_ext_state.

In case that more information than common link_ext_state is provided,
fill link_ext_substate also with the appropriate value.
