Just noticed that this one is not present at all in PPR 56176 Rev 3.06 - Jul
17, 2019 and that the umasks for the rest of the sub-counters in PMC0xAF
are right shifted by one when compared to those in Zen1. As a result,
the previous counter at umask 0x1 is no longer present.

I will update this counter to reflect what is documented in model 71h PPR 56176 Rev
3.06 - Jul 17, 2019.

-Vijay
