Want support for I350 temperature sensor
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* ... hc://:server-id=beowulf/motherboard=0/hostbridge=3/pciexrc=3/pciexbus=65/pciexdev=0?sensor=builtin group: protocol version: 1 stability: Private/Private resource fmri hc://:server-id=beowulf/motherboard=0/hostbridge=3/pciexrc=3/pciexbus=65/pciexdev=0?sensor=builtin group: authority version: 1 stability: Private/Private server-id string beowulf group: facility version: 1 stability: Private/Private sensor-class string threshold type uint32 0x1 (TEMP) units uint32 0x1 (DEGREES_C) reading double 47.000000
In addition, Ryan Zezeski also tested this on a discrete I350 he had and verified that things showed up in topo.
