nb/amd/mct_ddr3: Set the NBP0 read latency from P0 trained values
During maximum read latency training on Family 15h processors,
the maximum read latency was incorrectly set from the NBP1
value instead of the correct NBP0 value.
Modify maximimum read latency training to explicitly operate
on the NBP0 value, and store the previously calculated NBP1
value for reference by other portions of the training algorithm.
