superio/ite/common: Add temperature limits
Add devicetree options to set temperature limits that are used to alarm
user when temperature exceeds defined values.
Audio alerts by superio are not implemented yet, but since limits are
visible to userland, some software might use them as is. For instance,
lm-sensors displays "ALERT" when temperature exceeds limits.
