ARM: shmobile: kzm9d 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.

Note that we have to keep the "console=ttyS1,115200n81" parameter in
chosen/bootargs, else the console will use the default setting of 9600
baud.
