Revert "nb/amd/mct_ddr3: Enable DIMM parity when RDIMMs installed"

This reverts commit f961becc433bf23fc8744fdfd757f0cdb75c2c62.

On studying the BKDG more closely this is not the correct place
    to enable DIMM parity.  Further patches to clarify the parity
    setup process on Family 15h are forthcoming.
