Oh boy! I sent you and myself on wild goose chase! Really sorry about
messing up in the report of bug.

It is not dtbs_check, it is building dtbs with W=2 that generates this
warning. dtc 1.6.0 is sufficient to reproduce this behavior.

Using v5.10-rc1 as baseline (happens the same with next-20201113 as
		well.

v5.10-rc1: https://pastebin.ubuntu.com/p/Pn9HDqRjQ4/ (recording:

v5.10-rc1 + 1st patch in the series(since we are testing):
