    umbim: support multiple-valued configuration fields
    
    MBIM supports multiple values for IP address and DNS server, and such
    configuration is available through output of MBIM. Use new helper
    method to support adding multiple addresses and DNS servers to static
    interfaces for both IPv4 and IPv6.
