Have a newline between property list and child node.

This okay status doesn't seem really necessary to me.  If it does,
please put it at the end of property list.

Drop this newline, as in general we do not add newline in middle of

Have a newline between nodes.

Sort device nodes under bus in order of unit address.  That said,
stdp2690@72 should go before stdp4028@73.
