[PATCH] small MCA cleanups

The patch below does the following cleanups in the MCA code:
- make some needlessly global code static
- remove three unused global functions from mca-legacy.c (two of them
  were EXPORT_SYMBOL'ed); this should IMHO be safe since mca-legacy
  is not an API drivers should move to
