leds-lp5523: turn off the LED engines on unloading the driver



The LP5523 has 3 engines which are used for running LED patterns.
These engines should be off while unloading the driver.
Obviously, LP5523 platform data are used for releasing the resource
such like enable()/release_resource(), but these are not mandatory.
Therefore this patch is required without the platform data dependency.
