The led identifer should refer to devicetree ordering, not to the index
used by the controller. This way, it will be possible to deactivate
some leds or to reorganize the indexing if necessary.

The LP50XX family has a specific register to reset the configuration to
default state from any other state. Use this instead of relying on the
manual configuration of registers during startup.

Add support for LP5009, LP5012, LP5018 and LP5024 devices which only

Also, update application sample to run on all these new supported
devices.
