There is include/dt-bindings/leds/common.h with LED_FUNCTION_*

The choice for "status" was because of

And those known names do not really come with an explanation of their
meaning. Names like "bluetooth" seem obvious, but "activity" or
"indicator" leave a lot of room for speculation.

The choice in numbers was inspired by labels on the box, which i wanted
to reflect in some way.
