PCI/PM: Run resume fixups before disabling wakeup events

pci_pm_resume() and pci_pm_restore() call pci_pm_default_resume(), which
runs resume fixups before disabling wakeup events:

  static void pci_pm_default_resume(struct pci_dev *pci_dev)
  {
    pci_fixup_device(pci_fixup_resume, pci_dev);
    pci_enable_wake(pci_dev, PCI_D0, false);
  }

pci_pm_runtime_resume() does both of these, but in the opposite order:

  pci_enable_wake(pci_dev, PCI_D0, false);
  pci_fixup_device(pci_fixup_resume, pci_dev);

We should always use the same ordering unless there's a reason to do
otherwise.  Change pci_pm_runtime_resume() to call pci_pm_default_resume()
instead of open-coding this, so the fixups are always done before disabling
wakeup events.

pci_pm_default_resume() is called from pci_pm_runtime_resume(), which is
under #ifdef CONFIG_PM.  If SUSPEND and HIBERNATION are disabled, PM_SLEEP
is disabled also, so move pci_pm_default_resume() from #ifdef
CONFIG_PM_SLEEP to #ifdef CONFIG_PM.
