[Tomasz Nowicki]

Patches can be found:
https://github.com/semihalf-nowicki-tomasz/linux.git (its-acpi-v5)

Since this series depends on pending ARM64 ACPI PCI support, please pull:
https://github.com/semihalf-nowicki-tomasz/linux.git (its-pci-acpi-v5)
The its-pci-acpi-v5 git branch contains submitted patches along with
the useful PCI patches from the test point of view.

Series has been tested on Cavium ThunderX server.

v4 -> v5
- rebased against v4.7-rc1
- drop generic layer and call IORT functions directly
- improve resource abstraction and string formatting

v3 -> v4
- rebased against v4.5
- add ACPI support for IRQ domain handling on a per-device basis
- reorder domain setup step
- improve error handling
- code style improvements

v2 -> v3
- rebased on top of 4.4
- fixes and improvements for redistributor init via GICC structures
- fixes as per kbuild reports

v1 -> v2
- rebased on top of 4.4-rc4
- use pci_msi_domain_get_msi_rid for requester ID to device ID translation
