stdout-path can now take a config too (including the rate), which will
avoid any reliance on the serial core choosing the right rate by
default.

If you have an alias serial0, this could be:

	stdout-path = "serial0:115200n8";

Otherwise you can use the full path instead of serial0.

That's documented in Documentation/devicetree/bindings/chosen.txt
