[LEDE-DEV] [PATCH 1/2] lantiq: specify console using stdout-path instead of cmdline argument

Hi,
It looks like the kernel prefers the console parameter given in the boot
command line over the stdout-path parameter. On some boards the boot
loader provides this parameter to the kernel and then the serial does
not work. At least the VR200v, ARV4518pw and ARV7518pw are affected:
https://bugs.lede-project.org/index.php?do=details&task_id=350
I assume more devices are affected, so I would suggest to add the
bootargs parameter with a serial console again for the next release and
then we can try to fix it after the next release.
Will you prepare a patch?
