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
