Revert "nb/amd/mct_ddr3: Disable MCE framework during DRAM training"

After substantial testing it has been determined that it is neither
    required nor safe to disable the DRAM MCA during initial startup.

This (mostly) reverts commit c094d9961144871c472698c41ce634e58abb6a32.
    The minor debugging enhancements from that commit were left in place.
