broadband-modem-qmi: disable signal/access-tech polling if indications enabled

Browse Source 
We can rely on QMI indications when the signal quality and access tech
changes happen, instead of doing explicit polling.

The modem will run the signal quality retrieval once, and then just
rely on indications, with polling disabled:

  ModemManager[278759]: <debug> [1606862198.230492] [modem1] signal strength (lte): -79 dBm
  ModemManager[278759]: <debug> [1606862198.230520] [modem1] signal strength: -79 dBm --> 55%
  ModemManager[278759]: <debug> [1606862198.230583] [modem1] access technology changed (unknown -> lte)
  ModemManager[278759]: <debug> [1606862198.230654] [modem1] signal quality updated (55)
  ModemManager[278759]: <debug> [1606862198.230675] [modem1] periodic signal quality and access technology checks not rescheduled: unneeded or unsupported
  ModemManager[278759]: <debug> [1606862198.230692] [modem1] periodic signal checks disabled
