Contribution description
This adds the configuration for the on-board DotStar/APA102 LED for the adafruit-itsybitsy-nrf52. I based the change on the board definitions for the adafruit-itsybitsy-m4, which also has a DotStar.
I also fixed a small error in the doc. The other LED is red, not blue. See here (I can also verify by looking at the board in person):
Testing procedure
I tested this on the board using the program in
tests/drivers/apa102
and all looks correct to me.Issues/PRs references
