arm64: tegra: Add support for NVIDIA Shield TV Pro 2019

Browse Source 
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.
