PCI: Remove pci_ats_enabled()
Remove pci_ats_enabled(). There are no callers outside the ATS code itself. We don't need to check ats_cap, because if we don't find an ATS capability, we'll never set ats_enabled. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Joerg Roedel <jroedel@suse.de>
