Therefore, remove the mac_port_config member from ID_MT7988 in mt753x_table. Before calling priv->info->mac_port_config(), if there's no mac_port_config member in mt753x_table, exit mt753x_mac_config() successfully. Remove calling priv->info->mac_port_config() from the sanity check as the sanity check requires a pointer to a mac_port_config function to be non-NULL. This will fail for MT7988 as mac_port_config won't be a member of its info table.
