[ Upstream commitccc2f5a436] On MMIO devices (e.g. MT7988 or EN7581) unicast traffic received on lanX port is flooded on all other user ports if the DSA switch is configured without VLAN support since PORT_MATRIX in PCR regs contains all user ports. Similar to MDIO devices (e.g. MT7530 and MT7531) fix the issue defining default VLAN-ID 0 for MT7530 MMIO devices.
