I think this shows the big problem with using binman today.  For the
common case of ARM, where we sync in the dts* files from upstream, this
will add hunks that must not be overwritten each time.

Looking at scripts/Makefile.lib::cmd_fdt I wonder if we couldn't come up
with some wildcard rule and check if, somewhere CONFIG'd ? $(BOARDDIR)/
? u-boot.dtsi exists add in -include that/file.dtsi to the CPP rule so
that we can keep the parts that will never get upstream separate.
