leds-lp55xx: clean up deinit leds in lp5521/5523
To make LED unregistration code simple, new function, _unregister_leds() is added in each driver. This patch is a preceding step for lp55xx common driver architecture. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>
