Enable ATS on device-tree based systems, and factor the common ATS
enablement checks into pci_enable_ats().

Since v1 [1] I added acks and review tags, simplified patch 3 and tried
to clarify the comment in patch 2.

I'd like acks or comments on the following patches:
* PCI on patches 2, 3 and 5
* Arm SMMUv3 on patch 7
* Intel VT-d on patch 8
* arm64 DT on patch 10 

Thanks,
Jean
