Later revisions of PPRs that post-date the original Family 17h events
submission patch add these events.

Specifically, they were not in this 2017 revision of the F17h PPR:

Processor Programming Reference (PPR) for AMD Family 17h Model 01h, Revision B1 Processors Rev 1.14 - April 15, 2017

But e.g., are included in this 2019 version of the PPR:

Processor Programming Reference (PPR) for AMD Family 17h Model 18h, Revision B1 Processors Rev. 3.14 - Sep 26, 2019
