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.

Uhu, it's growing, now we have "lite". No, this is way too ambiguous.

NAK. Use PMIC compatibles.

There is no difference in this example, drop.

Drop as well.
