revisions. For now, the driver only uses the 16-bit mode on the
IT8716F and IT8718F.
The IT8726F is just bit enhanced IT8716F with additional hardware
for AMD power sequencing. Therefore the chip will appear as IT8716F
to userspace applications.
Temperatures are measured in degrees Celsius. An alarm is triggered once
when the Overtemperature Shutdown limit is crossed.
