Description

In 9747 we added support for Intel's PPIN feature to facilitate the use of CPU auto-replace. AMD added support for that. This generalizes the previous implementation to add support for AMD.

To test this, I ran this on and AMD system with a Rome chip and found that PPIN works and I had a serial number on the processor node in topo.
