cpu/amd/fam10h-fam15h: Honor CMOS option to disable CPB (core boost)
On certain systems and CPUs Core Performance Boost (CPB) may cause sporadic system lockups. This issue is also somewhat known on the various proprietary BIOSes, therefore it seems to be a hardware incompatibility when present.
Allow the user to disable CBP if needed.
