x86, mce, cmci: define MSR names and fields for new CMCI registers
Impact: New register definitions only CMCI means support for raising an interrupt on a corrected machine check event instead of having to poll for it. It's a new feature in Intel Nehalem CPUs available on some machine check banks. For details see the IA32 SDM Vol3a 14.5 Define the registers for it as a preparation for further patches.
