Subject: [PATCH v2 2/3] dt-bindings: leds: is31fl32xx: convert the binding
 to yaml

From: Lucca Fachinetti <luccafachinetti@...il.com>

Keep the old maintainers field as is.
Add datasheets for reference, NB that I was not able to find an
up-to-date, funtional direct URL for si-en products datasheet
so they were skipped.
