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.

The Jetson TX1 Development Kit is the successor of the Jetson TK1. The
Jetson TX1 is composed of the Jetson TX1 module (P2180) that connects to
the P2597 I/O board. It comes with a 1200x1920 MIPI DSI panel connected
via the P2597's display connector.

The NVIDIA P2597 I/O board is a carrier board for the Jetson TX1 module
and together they are also known as the Jetson TX1 Developer Kit. The
I/O board provides an RJ45 connector routed to the network adapter that
is part of the Jetson TX1 module. It exposes many other connectors such
as SATA, USB 3.0, HDMI, JTAG and PCIe, among others, as well. Dedicated
connectors allow display and camera modules to be attached. A full-size
SD slot is provided to extend storage beyond the 32 GiB of eMMC found
on the Jetson TX1 module.

The NVIDIA Jetson TX1 is a processor module that features a Tegra210 SoC
with 4 GiB of LPDDR4 RAM attached, a 32 GiB eMMC and other essentials.

It is typically connected to some I/O board (such as the P2597) that has
the connectors needed to hook it up to the outside world.

The NVIDIA P2571 is an internal reference design that's very similar to
the P2371, but targetting different use-cases.

The NVIDIA P2371 is an internal reference design that uses a P2530
processor module hooked up to a P2595 I/O board and an optional display
module for a 1200x1920 MIPI DSI panel.

The NVIDIA P2595 I/O board is used in several reference designs and has
the connectors to connect the P2530 compute module to the outside world.
It features a USB 3.0 network adapter, a USB 3.0 port, an HDMI port, a
SATA port, an audio codec, a microSD card slot and a display connector,
among others.

The NVIDIA P2530 is a processor module used in several reference designs
that features a Tegra210 SoC, 4 GiB of LPDDR4 RAM, 16 GiB eMMC and other
essentials. It is typically connected to some I/O board that provides
the connectors needed to hook it up to the outside world.

Also known as Tegra X1, the Tegra210 has four Cortex-A57 cores paired
with four Cortex-A53 cores in a switched configuration. It features a
GPU using the Maxwell architecture with support for DX11, SM4, OpenGL
4.5, OpenGL ES 3.1 and providing 256 CUDA cores. It supports hardware
accelerated en- and decoding of various video standards including
H.265, H.264 and VP8 at 4K resolutions and up to 60 fps.

Besides the multimedia features it also comes with a variety of I/O
controllers such as GPIO, I2C, SPI, SDHCI, PCIe, SATA and XHCI, to
name only a few.

Add a SoC-level device tree file that describes most of the hardware
available on the SoC. This includes only hardware for which a device
tree binding already exists or which is trivial to describe.

NVIDIA Tegra132 (also known as Tegra K1 64-bit) is a variant of Tegra124
but with 2 Denver CPUs instead of the 4+1 Cortex-A15. This adds the DTSI
file for the SoC, which is mostly similar to the one for Tegra124.
