Geert Uytterhoeven 59ab5bff23 ARM: shmobile: kzm9g-reference dts: Add chosen/stdout-path
Add a stdout-path property so that automatic console selection works
in the absence of a "console=" parameter on the kernel command line.
In addition, this will allow the PM domain code to find the PM domain
for the console device.

Note that we have to keep the "console=ttySC4" parameter in
chosen/bootargs, else we only get console messages on tty0.
