ARM64: tegra: Add chosen node for tegra132 norrin

The NVIDIA bootloader, nvtboot, expects the "chosen" node to be present in the device-tree blob and if it is not then it fails to boot the kernel. Add the chosen node so we can boot the kernel on Tegra132 Norrin with the nvtboot bootloader.

v1 -> v2 changes:
- minor fixes to commit message

Ideally, we would like to get this into v4.5 as a fix for Tegra132 Norrin so that we can enable booting this board as part of our automated testing setup for Tegra [0][1]. Thierry suggested I send this directly as a fix 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:
