Arlec ceiling fan remote: merge in identical sulion device

Missed when accepting PR that the submission was identical.

- suspect the product_id is incorrect (maybe model_id from cloud
  data), but it doesn't really matter.

Both devices were detected as 100% match for PR #2484, except the
number of speed steps is different, so that one does need a new
config.
