description:
Update some AMD CPUID bits:

- Rename FSREP_MOV to FSRM.
- Add Memory Bandwidth Enforcement (MBE)
- Add AMD's PPIN. Rename CPUID_SEF_PPIN to CPUID_SEF_INTEL_PPIN.
- Add Collaborative Processor Performance Control (CPPC).
- Add HOST_MCE_OVERRIDE.
- Add some unknown bits as Bxx.
- Add comments.
- Use __BIT().
