[PATCH 2/3] powerpc/pseries: Disable PRRN memory device tree trigger

[Tyrel Datwyler]

Memory affintiy updates as currently implemented have proved unstable.

This patch comments out the PRRN hook for the time being while we
investigate how to either stablize the current implementation or find a
better approach.
