hwmon: (k8temp) Differentiate between AM2 and ASB1

Commit 8bf0223ed515be24de0c671eedaff49e78bebc9c (hwmon, k8temp: Fix
temperature reporting for ASB1 processor revisions) fixed temperature
reporting for ASB1 CPUs. But those CPU models (model 0x6b, 0x6f, 0x7f)
were packaged both as AM2 (desktop) and ASB1 (mobile). Thus the commit
leads to wrong temperature reporting for AM2 CPU parts.

The solution is to determine the package type for models 0x6b, 0x6f,
0x7f.

This is done using BrandId from CPUID Fn8000_0001_EBX[15:0]. See
"Constructing the processor Name String" in "Revision Guide for AMD
NPT Family 0Fh Processors" (Rev. 3.46).
