hwmon: (k8temp) Fix temperature reporting for ASB1 processor revisions
Reported temperature for ASB1 CPUs is too high.
Add ASB1 CPU revisions (these are also non-desktop variants) to the
list of CPUs for which the temperature fixup is not required.
Example: (from LENOVO ThinkPad Edge 13, 01972NG, system was idle)
Current kernel reports
$ sensors
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +74.0 C
Core0 Temp: +70.0 C
Core1 Temp: +69.0 C
Core1 Temp: +70.0 C
With this patch I have
$ sensors

Adapter: PCI adapter
Core0 Temp: +54.0 C
Core0 Temp: +51.0 C
Core1 Temp: +48.0 C
Core1 Temp: +49.0 C
