True. I guess this is somewhat redundant here since the .dtsi file
already sets it to "disabled". Given how it is rather unusual for a
board's DTS file to not enable a node I think there would be some
advantage in keeping this explicitly to avoid confusion. Alternatively
perhaps a comment in the DTS file about why this isn't enabled by
default would be a good replacement.
