Kenji Kaneshige d391f00f0e PCI hotplug: fix wrong assumption in acpi_get_hp_hw_control_from_firmware ...

Current acpi_get_hp_hw_control_from_firmware() has a assumption that
pci_bus->self is NULL on a PCI root bus. But it might not be true on
some platforms. Because of this wrong assumption, current
acpi_get_hp_hw_control_from_firmware() might cause endless loop. We
must check pci_bus->parent instead.
