backlight: lp855x_bl: support new LP8557 device
LP8557 is one of LP855x family device, but it has different register map and initialization process. To support this device, device specific configuration is done through the lp855x_device_config structure. Few register definitions are fixed for better readability. BRIGHTNESS_CTRL -> LP855X_BRIGHTNESS_CTRL DEVICE_CTRL -> LP855X_DEVICE_CTRL EEPROM_START -> LP855X_EEPROM_START EEPROM_END -> LP855X_EEPROM_END EPROM_START -> LP8556_EPROM_START EPROM_END -> LP8556_EPROM_END And LP8557 register definitions are added. New register function, lp855x_update_bit() is added.
