airoha: account for L2 overhead in PPE MTU configuration

The PPE egress MTU register and WAN MTU register compare against L2
frame length without FCS, as confirmed by the hardware reset value of
0x05EA (1514 = ETH_HLEN + 1500).

Account for VLAN_ETH_HLEN when programming these registers to prevent
valid VLAN-tagged frames from being incorrectly dropped by hardware.
