thermal/drivers/qcom-spmi-temp-alarm: Add support for GEN2 rev 2 PMIC peripherals

Add support for TEMP_ALARM GEN2 PMIC peripherals with digital major
revision 2.  This revision utilizes individual temp DAC registers
to set the threshold temperature for over-temperature stages 1 (warning),
2 (system shutdown), and 3 (emergency shutdown) instead of a single
register to specify a set of thresholds.
