arm64: dts: qcom: pm8998: Add pm8998 thermal zone
The thermal zone uses spmi-temp-alarm as sensor, the trip points
correspond to the PMIC thermal stages 1 and 2. The critical trip
point at 125°C disables the partial PMIC shutdown at stage 2.
Without an IIO input the sensor only reports a limited number of
temperatures:
- 37°C for temperatures below 105°C
- 107°C for temperatures >= 105°C and < 125°C
- 127°C for temperatures >= 125°C
(the numbers correspond to a stage 1 threshold of 105°C)
