Using node paths to extend or override a device tree node is error
prone. If there was a typo error, a new node will be created instead of
extending the existing node. This will lead to run-time errors that
could be hard to detect.
A mistyped label on the other hand, will cause a dtc compile error
(during build time). This also reduces the indentation making the code
easier to read.
