description:
Update to support Family 15h Model 60 temperature sensors.
Changes based on FreeBSD amdtemp driver changes by Conrad Meyer.
XXX: Some code duplication between this driver and amdtemp as
parts of the 15h refresh code share more in common with
older CPUs while accessing the device more like 17h.
