[ Upstream commit cbbf09b5771e6e9da268bc0d2fb6e428afa787bc ]
DSA's idea of optimizing out multicast flooding to the CPU port leaves
quite a few holes open, so it should be reverted.
The mt7530 driver is the only new driver which added a .port_set_mrouter
implementation after the reorg from commit a8b659e7ff75 ("net: dsa: act
as passthrough for bridge port flags"), so it needs to be reverted
separately so that the other revert commit can go a bit further down the
git history.
Fixes: 5a30833b9a16 ("net: dsa: mt7530: support MDB and bridge flag operations")
