'linux,stdout-path' has been deprecated for some time in favor of

Search and replace all the of occurrences with 'stdout-path'.

This patch looks OK.

But please remember that not all device trees are generated with dtc, we
still have machines in the wild that have firmware which use
"linux,stdout-path" and may never be updated.
