[PATCH v5 08/11] PCI: PM: Use pci_power_manageable() in pci_pm_poweroff_noirq()

Devices with no subordinate should be put into D3 during hibernate, but
devices that have bridge_d3 set should also be put to sleep during
hibernate. Adjust the check in pci_pm_poweroff_noirq() to use
pci_power_manageable() to cover those as well.
