'linux,stdout-path' has been deprecated for some time in favor of
'stdout-path'. Now dtc will warn on occurrences of 'linux,stdout-path'.
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.

Absolutely. The core code still supports both.

The only scenario I could come up with is someone has an old
bootloader that only understands linux,stdout-path and modifies it and
they update the dtb. We may end up with both properties with
stdout-path taking preference.
