No, because that grabs PINs that might or might not be supposed to be used for that, it leaves clocks and regulators enabled, which draw power, to no end. And that's even worth since most boards will not use it. You can put the definition of the nodes in the DTSI, but the final status will have to be in the (relevant) DTS.
