If CONFIG_PCI_ATS is not set, building fails:

drivers/iommu/arm-smmu-v3.c: In function arm_smmu_ats_supported:
drivers/iommu/arm-smmu-v3.c:2325:35: error: struct pci_dev has no member named ats_cap; did you mean msi_cap?
  return !pdev->untrusted && pdev->ats_cap;
                                   ^~~~~~~

ats_cap should only used when CONFIG_PCI_ATS is defined,
so use #ifdef block to guard this.

Fixes: bfff88ec1afe ("iommu/arm-smmu-v3: Rework enabling/disabling of ATS for PCI masters")

v2: Add arm_smmu_ats_supported() of no CONFIG_PCI_ATS
