voltorb: add charger thermistor function
The OEM thermal test needs high temperature protection,
so add the temp-sensors to EC.
BUG=b:263700449
BRANCH=corsola
TEST=1. Use `ectool temps all` can see charger-thermistor
temperature value.
2. The ap shutdown when thernistor reaches
the temperature protection value.
