EDAC, mce_amd: Get rid of most struct cpuinfo_x86 uses

Browse Source 
struct mce.cpuid contains CPUID(1).EAX which contains family, model and
stepping and thus has enough information for our purposes. Thus get rid
of some external dependencies which are not really needed.

No functionality change.
