So I'm not 100% sure on how to proceed here exactly.  We have a few
things to consider.  First, I bet the generic dtb is good enough for
loading up and booting to Linux (and loading/passing a different,
complete and board specific DTB).  Second, we have the (reasonable)
set of patches and discussion to make the DTB that we use available
easily so that it could be passed on to Linux (or EFI apps or whatever).
So, this is probably the right thing to do in the long run, but is also
another data point in the "but we need to think and talk about if some
platforms really shouldn't be shipping their full FT on the HW
somewhere".

This is the default, you can drop it.
