iommu/arm-smmu-v3: Fix build error without CONFIG_PCI_ATS
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")
