"off" seems unused, this should be "suspend", however the difference
between the two states is already handled by the enable-gpio in the
driver, so you can omit the second state

Sorry for not being clear, I was okay with the gpio- prefix in the node
name, but I intended to ask to remove it from the label..

Please add a \n before status in nodes where there's more than just
that property
