Currently BIT(MT7530_CPU_PORT) is added to new_members, even though mt7530_port_vlan_add() will be called on the CPU port too. Let DSA core decide when to call port_vlan_add for the CPU port, rather than doing it implicitly. We can do autonomous forwarding in a certain VLAN, but not add br0 to that VLAN and avoid flooding the CPU with those packets, if software knows it doesn't need to process them.
