pci_mmcfg_list.
pci_acpi_set_companion() and acpi_pci_get_segment() are defined
using sysdata of generic ACPI host controller so that PCI domain
and ACPI companion are set in PCI code rather than platform code.
This code is currently enabled only for ARM64.

This patch is purely rearranging code, it should not have any

was done with an arch_init call
- remove unneeded pci_bus_add_devices call and fix MCFG saving code
- Added a patch to ACPI pci_root.c to handle arm64 PCI IO resources
