Subject: [PATCH] PCI/ATS: Remove unused PRI and PASID stubs
The following functions are only used by amd_iommu.c and intel-iommu.c
(when CONFIG_INTEL_IOMMU_SVM is enabled). CONFIG_PCI_PRI and
CONFIG_PCI_PASID are always defined in those cases, so there's no need for
the stubs.
pci_enable_pri()
pci_disable_pri()
pci_reset_pri()
pci_prg_resp_pasid_required()
pci_enable_pasid()
pci_disable_pasid()
Remove the unused stubs.
