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.
