[PATCH v1 9/9] PCI: PM: Set power.strict_midlayer in pci_pm_init()

["Rafael J. Wysocki" <rjw@xxxxxxxxxxxxx>]

From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

The PCI bus type does not expect its runtime PM callbacks,
pci_pm_runtime_suspend() and pci_pm_runtime_resume(), to be invoked at
any point during system-wide suspend and resume, so make it express
that expectation by setting power.strict_midlayer for all PCI devices.
