hwmon: (k8temp) Warn about fam F rev F errata

Browse source

Add warning about wrong CPU temperature readouts on all fam F rev F.

The allowed combinations of processors ensure that all processors
in a multisocket system have similar characteristics, e.g.

(1) provide temperature sensor interface (>=RevC && <RevF)
(2) are affected by erratum #141 (>=RevF)

Thus it is sufficient to check the revision of the boot CPU.

For "mixed silicon support" refer to
"Revision Guide for AMD Athlon 64 and AMD Opteron Processors" (RevA-E) and
"Revision Guide for AMD NPT Family 0Fh Processors" (RefF-G).
