leds-lp55xx: use lp55xx_init_led() common function
lp5521_init_led() and lp5523_init_led() are replaced with one common function,
lp55xx_init_led().
Max channels is configurable, so it's used in lp55xx_init_led().
'LP5523_LEDS' are changed to 'LP5523_MAX_LEDS'.
lp55xx_set_brightness, lp55xx_led_attributes: skeleton
Will be filled in next patches.
