commands: of_dump: implement -p for printing properties only
Some boards rewrite root node properties like compatible and
serial-number. Checking them can be annoying, because the properties
have usually long scrolled by, by the time the device tree was
completely dumped. Add a -p option to print only properties.
-p -n (print only node names AND only properties) is interpreted
to cancel each other out, so the whole device tree is dumped normally.
