This will be a but painful for projects like OpenWrt or Buildroot. They
have scripts that look for dtb files in specific directories. Now they
will have to be made kernel-version-aware which may not be an option.

Still I think it's a nice & needed cleanup!

Just in case someone knows some intermediate solution let me know
please.
