net: airoha: Rely on airoha_eth struct in airoha_ppe_flow_offload_cmd signature 



Rely on airoha_eth struct in airoha_ppe_flow_offload_cmd routine
signature and in all the called subroutines.
This is a preliminary patch to introduce flowtable offload for traffic
received by the wlan NIC and forwarded to the ethernet one.
