For the particular case this seems quite reasonable; the conditional
inclusion of this file would indeed allow us to enable all the nodes at
once.
But I find it hard to navigate the dts files when the information they
are spread out over multiple files and the current split has rather
clear rules of what goes where.
Further more this probably not going to be the only thing that differs
between engineering devices and production devices, but I don't think
this split would scale to the various other cases.
