1. Use stdout.
2. Drop earlycon, it is for debugging, not regular mainline usage.
I see that bcm4708.dtsi which this device tree includes already describes
stdout-path with the same value so I'll just get rid of the chosen node
here.

Why is this outside of soc? Both soc node and soc DTSI?
I don't maintain the SoC device tree files so I don't know. The nvram node
doesn't exist on any of the device tree files included by this device tree.
