net: airoha: Refactor src port configuration in airhoha_set_gdm2_loopback

Browse source

AN7583 chipset relies on different definitions for source-port
identifier used for hw offloading. In order to support hw offloading
in AN7583 controller, refactor src port configuration in
airhoha_set_gdm2_loopback routine and introduce get_src_port_id
callback.
