PCI/ATS: Restore EXPORT_SYMBOL_GPL() for pci_{enable,disable}_ats()
Commit d355bb209783 ("PCI/ATS: Remove unnecessary EXPORT_SYMBOL_GPL()")
unexported a bunch of symbols from the PCI core since the only external
users were non-modular IOMMU drivers. Although most of those symbols
can remain private for now, 'pci_{enable,disable_ats()' is required for
the ARM SMMUv3 driver to build as a module, otherwise we get a build
failure as follows:
| ERROR: "pci_enable_ats" [drivers/iommu/arm-smmu-v3.ko] undefined!
| ERROR: "pci_disable_ats" [drivers/iommu/arm-smmu-v3.ko] undefined!
Re-export these two functions so that the ARM SMMUv3 driver can be build
as a module.
