[PATCH] perf: ARM_SMMU_V3_PMU should depend on ARM_SMMU_V3

[Geert Uytterhoeven]

There is no point in monitoring transactions passing through the SMMU
when ARM Ltd. System MMU Version 3 (SMMUv3) Support is disabled.
Hence replace the dependency on ARM64 by a dependency on ARM_SMMU_V3
(which implies the former).

This caught my eye after commit 7c3f204e544dfa37 ("perf/smmuv3: Remove
build dependency on ACPI") in arm64/for-next/core.

Perhaps my understanding is wrong? Is there anything to monitor when
ARM_SMMU_V3=n?
