Angel Pons f14880934b Haswell NRI: Use final timings after basic training
For "basic" (initial) memory training, we use larger-than-usual timings
for a few things, namely tCMD and tXP. After basic training is done, we
can switch to the final timings for the training steps that follow (not
many at the moment). Without this, NRI keeps using the training timings
at all times, which results in slightly lower performance (likely to go
unnoticed unless benchmarking the system).

Tested on Asrock B85M Pro4, still boots to Arch Linux.
