    Revert "nb/amd/mct_ddr3: Fix RDIMM training failure on Fam15h"
    
    This reverts commit fec8872c9dee4411ba1a89fc8ec833a700b476c6.
    
    The commit introduced a regression which is causing MC4 failures
    when 8 RDIMMs are populated in a configuration with a single CPU
    package. Using just 4 RDIMMs, the failure does not occur.
    
    After reverting the commit, I tested configurations with
    1 CPU (8x8=64GB) and 2 CPU packages (16x8=128GB) using an
    Opteron 6276. The MC4 failures did not occur anymore.
