[PATCH v2 17/17] arm64: tegra: Add support for NVIDIA Shield TV Pro 2019

[Aaron Kling via B4 Relay]

From: Aaron Kling <webgeek1234 at gmail.com>

Add initial device-tree support for NVIDIA Shield TV Pro 2019 (a.k.a
MDarcy) based up the Tegra210B01 SoC with 3 GiB of LPDDR4 RAM.

This is very basic, intended for checking initial Tegra210B01 support.
More complete support for the device will be added later.
