After patch "Add back an error message, restructured" is applied,
a lot of the messages return, but hopefully keeping readability.
Note that the one message added back covers a number of error
locations.

Are there any additional key messages that you think I missed in
the add back an error message patch?

Keep in mind that many of the debug messages address malformed
dtb, which would be a bug in dtc.  It made sense for these to
exist while dtc was being modified, but now that you have
created and tested the dtc changes, I think most of those
debug messages no longer make sense for mainline code.
