PCI: Embed ATS info directly into struct pci_dev
The pci_ats struct is small and will get smaller, so I don't think it's worth allocating it separately from the pci_dev struct. Embed the ATS fields directly into struct pci_dev. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Joerg Roedel <jroedel@suse.de>
