[PATCH] acpi bridge hotadd: Export the interface to get PCI id for an ACPI handle

Export an acpi interface to get PCI domain/bus/devfn information from the
corresponding namespace handle.  Used by acpiphp code to transpate the device
handle of the hot-plugged root bridge to the corresponding pci location
information.
