I'd really prefer not to do that. There's going to be a long trail of
defconfig that will be sent at pretty much the same time that are not
going to have it and that will go unnotice for some time.

And there's obviously the useless churn in all the defconfig that are
not in the case where it makes sense to override DEFAULT_FDT_FILE.

Why not create a Kconfig boolean that allows to select whether or not
you want DEFAULT_FDT_FILE to be DEFAULT_DEVICE_TREE + .dtb or a custom
value.
