I think this should remain user choice. If its going to be selected,
then you might as well just remove the option altogether. Perhaps just
make the option default to yes.

Why bother? If the defconfigs select it then most users basing their
config from that will be just fine.

PROC_DEVICETREE is 100% optional, it's useful to get runtime access to
the contents of the device tree but it's not required for the kernel
to boot.
