[PATCH v3 11/13] PCI/ATS: Add PRI stubs

[Jonathan Cameron]

> The SMMUv3 driver, which may be built without CONFIG_PCI, will shortly gain
> PRI support. Partially revert commit c6e9aefbf9db ("PCI/ATS: Remove unused
> PRI and PASID stubs") to re-introduce the PRI stubs, avoiding more #ifdefs
> in the SMMU driver.
