Revert "iommu/vt-d: Retrieve IOMMU perfmon capability information"
This reverts commit 586e19c88a0cb58b6ff45ae085b3dd200d862153 which is
commit a6a5006dad572a53b5df3f47e1471d207ae9ba49 upstream.
This commit is pulled in due to dependency for:
8c91a4bfc7f8 ("iommu: Fix compilation without CONFIG_IOMMU_INTEL")
But the patch itself is part of a patchset, should not only include one,
and it lead to boot hang on on Kernel 6.1.83+ with Dell PowerEdge R770
and Intel Xeon 6710E, so revert it for stable 6.1.112
