illumos gate

I tested this by verifying that the smntemp driver came up and had temperature information, as well as that the other devices and drivers that are expected:

$ find /devices/pseudo | grep -i zen
/devices/pseudo/amdzen@0
/devices/pseudo/amdzen@0/smntemp@1
/devices/pseudo/amdzen@0/usmn@2
/devices/pseudo/amdzen@0/usmn@2:usmn.0
/devices/pseudo/amdzen@0/usmn@2:usmn.1
/devices/pseudo/amdzen@0/zen_udf@3
/devices/pseudo/amdzen@0/zen_udf@3:zen_udf.0
/devices/pseudo/amdzen@0/zen_udf@3:zen_udf.1

I also verified that the temperature sensors matched what I was seeing in ipmitool sensor remotely.
