ATS support for AMD IOMMU driver

Hi,

this patch-set implements support for ATS devices in the AMD IOMMU
driver. For that it uses the ATS capability implementation already
present in the core PCI code.

Jesse, patch 1/5 touches generic PCI code, can you please have a look at
it an ACK it if you think it is ok? The change basically move out the
declarations relevant for ATS into a header file under include/linux.
This header file will also be used later to put declarations for PRI
support there (which is also part of the ATS spec).

Any feedback appreciated.

Regards,

	Joerg
