PCI: Move ATS declarations in seperate header file
This patch moves the relevant declarations from the local header file in drivers/pci to a more accessible locations so that it can be used by the AMD IOMMU driver too. The file is named pci-ats.h because support for the PCI PRI capability will also be added there in a later patch-set.
