Subject: [RFC PATCH net-next 1/8] net: dsa: Move dsa_switch_tree final setup in separate function

In preparation for allowing a different API to register DSA switches,
move the end portion of dsa_setup_dst(), which binds a net_device with
its dsa_ptr, and setups the optional link polling routine into
dsa_setup_dst_end().
