[PATCH v2 16/17] arm64: tegra: Add Tegra210B01 support

From: Aaron Kling <webgeek1234 at gmail.com>

Also known as Tegra X1+, the Tegra210B01 has higher CPU and GPU clocks
than the original Tegra210.

Add a SoC-level device tree file that describes most of the hardware
available on the SoC. This is derived from the Tegra210 dtsi, as they
share a lot.
