Series [v7,1/2] leds: leds-lp50xx: Handle reg to get correct multi_index | expand

Commit Message

The led child reg node is the index within the bank, document that
and update the example accordingly.
The reg property in child node is limited to 0-2 since there are 3 leds
per bank, previous value in example was speculative.
