ACPI / scan: Simplify acpi_bus_extract_wakeup_device_power_package()
acpi_bus_extract_wakeup_device_power_package() is a static function with a single caller that supplies (device->handle, &device->wakeup). Simplify the interface so the caller need only supply "device". This makes it obvious that "wakeup", i.e., &device->wakeup, can never be NULL, so remove the unnecessary check for that.
