The patch is fine (and welcome, but for one nit below), but the
description needs to be better.

The main redundancy I can see is that node labels (like serial0, serial1
etc) are being redefined. So can you be clear on that. Also, the phandle
way of extending nodes is more "modern" (I dont quite recall if it was
common place back when the file was added in 2012).

Also, I would not call it "Refactor device tree layout" in subject. "use
phandles to extend nodes" is more apt.

Can you add an empty line after each node. This will make it consistent
with how its done in da850-lcdk.dts and da850-lego-ev3.dts
