MIPS: dts: qca: ar9132: use short references for dt nodes

Browse Source 
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.
