linux-dtb.inc: overlay the latest version from oe-core/master

Browse Source 
With recent kernel versions now using CPP and kernel headers, it's better
to use kernel's in-tree DTB compilation instead of building and using our
own DTC compiler externally. This overlays the changed approach from latest
oe-core/master into Dylan.
