Mika Westerberg ac86e8eeb0 PCI: Do not skip power-managed bridges in pci_enable_wake()
Commit baecc470d5 ("PCI / PM: Skip bridges in pci_enable_wake()") changed
pci_enable_wake() so that all bridges are skipped when wakeup is enabled
(or disabled) with the reasoning that bridges can only signal wakeup on
behalf of their subordinate devices.

However, there are bridges that can signal wakeup themselves.  For example
PCIe downstream and root ports supporting hotplug may signal wakeup upon
hotplug event.

For this reason change pci_enable_wake() so that it skips all bridges
except those that we power manage (->bridge_d3 is set).  Those are the ones
that can go into low power states and may need to signal wakeup.
