atmodem: Signal quality on quectel serial modems
As the default way of getting the signal quality with +CIND is also unstable on quectel serial modems (the same as on quectel EC21). In fact the signal quality is only updated on cell changes. Those trigger a manual AT+CSQ in ofono and get an update this way, but the URCs do not work. So we implement a quectelish way here as well. The quectelish way is very similar to the way ifx modems work. We can reuse their csq_notify function.
