Add temp-alarm device tree node and a default configuration for the
corresponding thermal zone for this PMIC. Temperatures are based on
downstream values.

With this config I'm getting this in dmesg, not sure if it's a warning
that should be solved or just an informative warning.
[ 0.268256] spmi-temp-alarm c440000.spmi:pmic@0:temp-alarm@2400: No ADC is configured and critical temperature is above the maximum stage 2 threshold of 140 C! Configuring stage 2 shutdown at 140 C.
As far as I can tell, based on downstream dts this PMIC doesn't have an
ADC.
