PCI Hotplug: acpiphp: get pci_bus from acpi handle correctly
We cannot simply call acpi_get_pci_dev() on any random ACPI handle
and hope that it works, because a PCI root bridge may not have
an associated struct pci_dev.
This is allowed per the PCI specification, and is referred to as a
non-materialized bridge.
So, depending on the type of PCI bridge that the handle points to,
use the appropriate interface to return the struct pci_bus correctly.
