ACPI / PM: Fix /proc/acpi/wakeup for devices w/o bus or parent
Fix /proc/acpi/wakeup for devices without bus or parent This patch fixes printing the wakeup status for devices without a bus or parent, such as laptop lid switches and sleep buttons. These devices have an empty physical_node_list, because acpi_bind_one is never run for them.
