nb/amd/mct_ddr3: Use antiphase to better center DQS window

The BKDG recommends the use of an antiphase window detection
algorithm to ensure that the DQS data eye is properly centered.

TEST: Booted both with DIMMs known to move the data eye into the
prior clock phase and DIMMs known to keep the data eye in the
current clock phase.
