You might have to resend so that the original patch shows up in the
ARM SoC maintainers' inbox.

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.

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:

Fixes: 0f279eb arm64: tegra: Add NVIDIA Tegra132 Norrin support

[1] http://nvtb.github.io/linux-next/

Forgot to mentioned that the differences for v1 -> v2 are just some
minor corrections to the commit message.
