Thanks.
APIs to get/set PCI slot status. Those functions are going to
be used by PowerNV PCI hotplug driver:
pnv_pci_get_device_tree()opal_get_device_tree()
pnv_pci_get_presence_state() opal_pci_get_presence_state()
pnv_pci_get_power_state()opal_pci_get_power_state()
pnv_pci_set_power_state()opal_pci_set_power_state()
Besides, the patch also exports pnv_pci_hotplug_notifier_{register,
unregister}() to allow registration and unregistration of PCI hotplug
notifier, which will be used to receive PCI hotplug message from
skiboot firmware in PowerNV PCI hotplug driver.
