Subject: [PATCH 08/11] ARM: dts: s3c24xx: override nods by label
Using full 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).
