Device tree node order sort tool

[Frank Li <Frank.li@nxp.com>]

All:
	I write a simple tools to sort device tree to make sure nodes and
properties sort as correct order.
	https://github.com/lznuaa/dt-format

	There are many dt files, which have node order trivial issue, when
try to upstream. To reduce reviewer's time, dt-format can help correct the
order.

	I just want to make sure my understand about node order is correct.

	Rule 1: node@hexvalue,  	order by hexvalue
	Rule 2: label: node,  		order by node name
	Rule 3: node, 			order by node name
	Rule 3: &label			order by label
	Rule 4: children node already after property
	Rule 5: "status" always is last one.
	Rule 6: property order as below list[unfinished], otherwise, order
	        by name.
