The datasheet says that the AT+QDAI audio routing configuration is saved
to non-volatile memory directly, and therefore needs a modem reset to be
applied.

This commits changes the audio routing configuration script to first
check for the current configuration, and only change it if it is
different from the one wanted.

The new configuration is then sent, and modem is reset to apply
configuration.
