net: airoha: Do not loopback traffic to GDM2 if it is available on the device 



Airoha_eth driver forwards offloaded uplink traffic (packets received
on GDM1 and forwarded to GDM{3,4}) to GDM2 in order to apply hw QoS.
This is correct if the device does not support a dedicated GDM2 port.
In this case, in order to enable hw offloading for uplink traffic,
the packets should be sent to GDM{3,4} directly.
