Currently, using fdt_fixup_stdout() on a device tree that is missing the relevant alias results in this:
WARNING: could not set linux,stdout-path FDT_ERR_NOTFOUND. ERROR: /chosen node create failed

FDT creation failed! hanging...### ERROR ### Please RESET the board ###
There is no reason for this to be a fatal error rather than a warning, and removing this allows for a smooth transition on a platform where the device tree currently lacks the correct aliases but will have them in the future.
Why do we need this patch - what platform?

Will some platforms will not boot correctly with this failing? Should we make your new feature a Kconfig options perhaps? I worry that it will become the default behaviour and then it will be hard to remove later.
