[PATCH 2/3] PCI/ATS: Remove unnecessary EXPORT_SYMBOL_GPL()

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>

The following functions are only used by the PCI core or by IOMMU drivers
that cannot be modular, so there's no need to export them at all:

  pci_enable_ats()
  pci_disable_ats()
  pci_restore_ats_state()
  pci_ats_queue_depth()
  pci_ats_page_aligned()

  pci_enable_pri()
  pci_restore_pri_state()
  pci_reset_pri()
  pci_prg_resp_pasid_required()

  pci_enable_pasid()
  pci_disable_pasid()
  pci_restore_pasid_state()
  pci_pasid_features()
  pci_max_pasids()

Remove the unnecessary EXPORT_SYMBOL_GPL()s.
