[PATCH 4/6] arm64: tegra: Add NVIDIA P2530 compute module support

[thierry.reding@gmail.com (Thierry Reding)]

From: Thierry Reding <treding@nvidia.com>

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