[RESEND PATCH 1/2] x86, mce: fixup mce naming nomenclature

[Borislav Petkov]

Prefix global/setup routines with "mcheck_" thus differentiating from
the internal facilities prefixed with "mce_". Also, prefix the per cpu
calls with mcheck_cpu and rename them to reflect the MCE setup hierarchy
of calls better.

There should be no functionality change resulting from this patch.
