On pseries, TLB multihit are reported as D-Cache Multihit. This is because
the wrongly populated mc_err_types[] array. Per PAPR, TLB error type is 0x04
and mc_err_types[4] points to "D-Cache" instead of "TLB" string. Fixup the
mc_err_types[] array.

Machine check error type per PAPR:
  0x00 = Uncorrectable Memory Error (UE)
  0x01 = SLB error
  0x02 = ERAT Error
  0x04 = TLB error
  0x05 = D-Cache error
  0x07 = I-Cache error
