nb/amd/mct_ddr3: Only initialize ECC bits once

The ECC check bits of all ECC DIMMS were inadvertently initialized
    twice in the same routine, significantly delaying startup.  Part
    of this was related to an obsolete MCA workaround that has been
    fixed through multiple commits, therefore the workaround is no
    longer needed.

Only initialize the ECC check bits once.
