You should consider putting this dts in a separate recipe, see 
https://docs.yoctoproject.org/ref-manual/classes.html#devicetree for how 
to do it.

It depends on what the kernel recipe is doing with that defconfig. Could 
also be trying to apply fragments afterwards for example. Without having 
a look at the recipe, it'll be difficult to tell. You haven't said to 
which recipe this bbappend is supposed to apply though and there are 
many ways and many kernel recipes around :)
