Thanks, I think it improves the readability of intent in the binding as
well.

To understand the impact better I grabbed the patch and diffed the
output of `make CHECK_DTBS=y aspeed/aspeed-ast2600-evb.dtb` before and
after applying it, but there was no significant difference in output.
Should that not demonstrate the errors being cleaned up? If not, what
should?
