mainboard/kgpe-d16|kcma-d8: Update memory test to include second PRNG stage

The existing memory test routine was insufficient to detect certain types
of bus instability related to multiple incompatible RDIMMs on one channel.

Add a PRNG second stage test to the memory test routine.  This second stage
test reliably detects faults in memory setup for RDIMM configurations that
also fail under the proprietary BIOS.
