powerpc/powernv: Functions to get/set PCI slot state
This exports 4 functions, which base on the corresponding OPAL
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()
