[Bridge] [PATCH net-next 3/9] net: dsa: stop setting initial and final brport flags

From: Vladimir Oltean <vladimir.oltean at nxp.com>

With the bridge driver doing that for us now, we can simplify our
mid-layer logic a little bit, which would have otherwise needed some
tuning for the disabling of address learning that is necessary in
standalone mode.
