Rafael J. Wysocki 2d55951368 ACPI / ACPICA: Avoid crashing if _PRW is defined for the root object
Some ACPI BIOSes define _PRW for the root object which causes
acpi_setup_gpe_for_wake() to crash when trying to dereference the
bogus device_node pointer.  Avoid the crash by checking if
wake_device is not the root object before attempting to set up the
"implicit notify" mechanism for it.

The problem was introduced by commit bba63a296f
(ACPICA: Implicit notify support) that added the wake_device argument
to acpi_setup_gpe_for_wake().
