Want support for I350 temperature sensor
100%
Description
The Intel I350 which is supported by the igb driver has a built-in thermal diode and optional support for an external temperature sensor indicated in its eeprom. This change adds support for the built-in thermal diode as I have not been able to find a discrete I350 with these features enabled in its EEPROM yet. Though extending it in such a case would be useful. This leverages the framework introduced in 12830.

To test this I ran these bits on a system that had the I350 and verified that it showed up in fmtopo. Here's an example of it showing up on a system with a single built-in I350:
rm@beowulf:~$ find /dev/sensors/
/dev/sensors/
/dev/sensors/temperature
/dev/sensors/temperature/cpu
/dev/sensors/temperature/cpu/procnode.0
/dev/sensors/temperature/pci
/dev/sensors/temperature/pci/41.0
/dev/sensors/temperature/pci/41.0/builtin
rm@beowulf:~$ pfexec /usr/lib/fm/fmd/fmtopo -V *sensor*

In addition, Ryan Zezeski also tested this on a discrete I350 he had and verified that things showed up in topo.
