Add compatible "qcom,spmi-temp-alarm-lite" for Temp alarm lite
peripherals. Temp alarm lite peripherals have two stages: warning and
shutdown, and use a pair of registers to configure warning interrupt
threshold temperature and an automatic hardware shutdown threshold
temperature.
When defining thermal zone trips for a temp alarm lite device the first
thermal zone trip is for warning alarm IRQ in HW, the second thermal
zone trip is purely for software to perform a controlled shutdown (no HW
support) and the third thermal zone trip is for automatic hardware
shutdown.
