I'd doubt we could completely script this with a generic rule without a
bunch of manual transformations. So I think either restructuring in the
kernel or when we move them out of the kernel makes more sense. We know
the problem is coming, but it is not yet a major, pressing issue.

OTOH, you could see how far you get by putting dts files in directories
by their board level compatible string vendor and put any include files
where ever they are included from. Of course, that is just my proposed
layout. I haven't heard any opinions on that layout.
