Subject: [RFC PATCH 0/4] MMCFG refactoring + PCI ACPI probing for ARM64

The patch set can be break down into two logic parts:
1. patch 1,2 - MMCONFIG code refacoring. MMCFG ACPI table has no arch
dependencies so it can be used across other architectures.
2. patch 3,4 aim for PCI ACPI probing on ARM64

Patches tested on Cavium ThunderX simulator with the latest ACPI ARM64 core set:

Tomasz Nowicki (4):
  x86, acpi, pci: Move arch-agnostic MMCFG code out of arch/x86/
    directory.
  x86, acpi, pci: Isolate new PCI mmconfig entry insertion.
  arm64, acpi, pci: Add arch specific functions for mmconfig driver.
  arm64, acpi, pci: Provide arch-specific calls for PCI host bridge
    dirver (PNP0A03).
