Geert Uytterhoeven 54389e981c ARM: dts: kzm9g: Update console parameters 
Change the console alias to "serial0", for consistency with other
boards (the first unlabeled serial port is always called "serial0").
This does change the serial console from /dev/ttySC4 to /dev/ttySC0.
Add the serial port config to "chosen/stdout-path", which requires
referring to the port by alias.
Drop the "console=" parameters from the kernel command line, as they're
no longer needed for DT-based platforms.
