x86, mce: Fix up MCE naming nomenclature

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.
