leds-lp55xx: use lp55xx common led registration function
LED class devices are registered in lp5521_register_leds() and lp5523_register_leds(). Two separate functions are merged into consolidated lp55xx function, lp55xx_register_leds(). Error handling fix: Unregistering LEDS are handled in lp55xx_register_leds() when LED registration failure occurs. So each driver error handler is changed to 'err_register_leds' Chip dependency: 'brightness_work_fn' and 'set_led_current' To make the structure abstract, both functions are configured in each driver. Those functions should be done by each driver because register control is chip-dependant work. lp55xx_init_led: skeleton Will be filled in next patch Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>
