I posted this one a while back, but I guess it dropped through the
cracks.  There's also the patch I sent you quite a long time ago that
adds a clarifying readme about the licensing situation - that might be
an idea for v1.1, too.

dtc: Remove header information dumping

Currently, when used in -Idtb mode, dtc will dump information about
the input blob's header fields to stderr.  This is kind of ugly, and
can get in the way of dtc's real output.

This patch, therefore, removes this.  So that there's still a way of
getting this information for debugging purposes, it places something
similar to the removed code into ftdump, replacing the couple of
header fields it currently prints with a complete header dump.
