leds-lp55xx: do chip specific configuration on device init
Chip specific function is configured when the device is initialized.
So _configure() is moved to each device init function.
If chip configuration gets failed, the device is de-initialized in
each _init_device(), not probe().
For compile error fix, function type declarations are added.
