Hi Neil,

This adds a driver for the SMMUv3 PMU into the perf framework.
It includes an IORT update to support PM Counter Groups.

IORT has no mechanism for determining device names so PMUs
are named based on their physical address.

Tested on Qualcomm QDF2400. perf_fuzzer ran for 4+ hours
with no failures.

Do you have the acpica support code? I'm currently
working on SMMUv3 MSI support and I would like to test
it with MSI support for PMCG as well.
