leds-lp55xx: use common lp55xx data structure in _probe()
LP5521 and LP5523 data structures have common features.
Use common lp55xx data structures rather than chip specific data.
Legacy code in probe is replaced with this new data structures.
lp55xx_chip : Common data between lp5521_chip and lp5523_chip
lp55xx_led : Common LED structure between lp5521_led and lp5523_led
lp55xx_platform_data : Common platform data between lp5521_platform_data and
lp5523_platform_data
