net: dsa: vsc73xx: Add bridge support 



This patch adds bridge support for the vsc73xx driver.

The vsc73xx requires minimal operations and ithe generic
dsa_tag_8021q_bridge_* API is sufficient.
The forwarding matrix is managed by vsc73xx_port_stp_state_set() ->
vsc73xx_refresh_fwd_map()i routine, which is called immediately after
.port_bridge_join() and .port_bridge_leave().
