platform/x86: thinkpad_acpi: Add LED_RETAIN_AT_SHUTDOWN to led_class_devs
Add the LED_RETAIN_AT_SHUTDOWN flag to the registered led_class_devs so that the LEDs do not get turned-off when reloading the driver and thus so that they also stay under default EC control when reloading the driver, unless explicitly overridden by the user.
