Note that the brokeness you describe also leads to stdout-path being
unable to put the console on any serial port but the first, as reported
here:
http://lists.infradead.org/pipermail/linux-arm-kernel/2015-February/323811.html

It always puts the console on the first serial port if CONFIG_VT_CONSOLE
is not enabled, even if the stdout-path property requests a different
serial port.
