I like this location and agree that having them in tree makes sense.
And putting them under boot isolates them from the kernel proper.
The reason I see to having them in tree is to ensure proper version
compatibility. This way there is no concern about which .dts version
will work with which kernel. In the future we can always pull them
out when things are more stable.
