Because bcm_sf2 implements its own dsa_switch_ops we need to export the
b53_br_flags_pre(), b53_br_flags() and b53_set_mrouter so we can wire-up
them up like they used to be with the former b53_br_egress_floods().

Fixes: a8b659e7ff75 ("net: dsa: act as passthrough for bridge port flags")

To be clear, I did not miss migrating .port_egress_floods towards
.port_bridge_flags, I just migrated what existed, and sf2 didn't have
it. So from a blame perspective, this patch should have:

Fixes: 53568438e381 ("net: dsa: b53: Add support for port_egress_floods callback")

However, your fix cannot be backported past the patch you blamed, so in
practice it makes no difference.
