ARM64: PCI: Add acpi_pci_bus_find_domain_nr()
Extend pci_bus_find_domain_nr() so it can find the domain from either:
- ACPI, via the new acpi_pci_bus_find_domain_nr() interface, or
- DT, via of_pci_bus_find_domain_nr()
Note that this is only used for CONFIG_PCI_DOMAINS_GENERIC=y, so it does
not affect x86 or ia64.
