Update signal strength indicator thresholds

Browse Source 
These are thresholds for RSSI so nothing is expected to be
greater than 0.
This will allow to have a better granularity (even if with some
modem, we are limited in the number of thresholds configured)

These new thresholds will give the following signal quality range:
  - 11% for -110 dBm
  - 30% for  -94 dBm
  - 50% for  -82 dBm
  - 70% for  -69 dBm
  - 90% for  -57 dBm

We are expecting to receive indication sreport every time the
signal strength crosses one of the configured thresholds.
