leds-lp55xx: clean up init function
lp5521/5523_init_device() are replaced with lp55xx common function, lp55xx_init_device(). Error handler in init_device: deinit function are matched with 'err_post_init' section in lp55xx_init_device(). Remove LP5523 engine intialization code: Engine functionality is not mandatory but optional. Moreover engine initialization is done internally with device reset command. Therefore, this code is unnecessary. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>
