net: airoha: Rely on airoha_gdm_dev pointer in airoha_is_lan_gdm_port()

Browse Source 
Rename airoha_is_lan_gdm_port in airoha_is_lan_gdm_dev. Moreover, rely
on airoha_gdm_dev pointer in airoha_is_lan_gdm_dev() instead of
airoha_gdm_port one.
This is a preliminary patch to support multiple net_devices connected to
the same GDM{3,4} port via an external hw arbiter.
