[RFC PATCH 0/3] ACPI PCI support for arm64

[Jayachandran C]

This is a very simple and generic implementation of a PCI host controller
based on ACPI. This approach does not pull in the MMCONFIG and ECAM code
from x86.

It is important for us to have a working ACPI based PCI host controller
implementation for arm64, so I thought I would post this as a simple
and less disruptive alternative.

This is tested with arm64 QEMU and OVMF. Comments are very welcome.

Thanks,
JC.
