The NVIDIA bootloader, nvtboot, expects the "chosen" node to be present

Add the chosen node so we can boot the kernel on Tegra132 Norrin with the
nvtboot bootloader.

to ARM-SOC. Let me know if this is ok. I have not included a "fixes" as it
may not be needed for all bootloaders, but if you need this we could put:
