MIPS: dts: qca: ar9132: use short references for dt nodes
Here are some Sascha Hauer's arguments for using aliases in the dts files: - using aliases reduces the number of indentations in dts files; - dts files become independent of the layout of the dtsi files (it becomes possible to introduce another bus {} hierarchy between a toplevel bus and the devices when you have to); - less chances for typos. if &i2c2 does not exist you get an error. If instead you duplicate the whole path in the dts file a typo in the path will just create another node.
