PCI/PM Runtime: Make runtime PM of PCI devices inactive by default

Browse source

Make the run-time power management of PCI devices be inactive by
default by calling pm_runtime_forbid() for each PCI device during its
initialization.  This setting may be overriden by the user space with
the help of the /sys/devices/.../power/control interface.

That's necessary to avoid breakage on systems where ACPI-based
wake-up is known to fail for some devices.
