net: airoha: Rely on net_device pointer in airoha_dev_setup_tc_block signature

Remove airoha_gdm_port dependency in airoha_dev_setup_tc_block routine
signature and rely on net_device pointer instead. Please note this patch
does not introduce any logical change and it is a preliminary patch to
support multiple net_devices connected to the GDM3 or GDM4 ports via an
external hw arbiter.
