nb/amd/mct_ddr3: Do not constantly reset read data timing registers to 0
During DQS receiver enable cycle training on Family 15h platforms the
read data timing registers were inadvertently set to zero on every
lane training attempt.
Ensure that the read data timing registers are correctly set after
each lane is trained in receiver enable cycle training. This allows
more than one RDIMM to function on a given DCT channel.
