CPUID_TO_STEPPING(cpuid) (not changed)

CPUID_TO_FAMILY(cpuid) (new)
CPUID_TO_MODEL(cpuid) (new)

Return the display family and the display model.
The macro names are the same as FreeBSD.

Contrary to the AMD implementation, it doesn't use xcalls to distribute

hyperthreading.
Also, it doesn't parse the vendor supplied file to pick the right

files with specific filenames. I'll commit a pkg for this in a minute
