Subject: [PATCH net-next 09/15] net: dsa: lantiq_gswip: use simple HSR offload helpers

Both the "gswip" and "gsw1xx" protocols use dsa_xmit_port_mask(), so
they are compatible with accelerating TX packet duplication for HSR
rings.

Enable that feature by setting the port_hsr_join() and port_hsr_leave()
operations to the simple helpers provided by DSA.
