[U-Boot] [PATCH 1/4] ARM: tegra: add SoC-level hook for board_late_init()

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

Extend the Tegra186 implementation of board_late_init() to call a per-SoC
"hook" function. This will allow SoC-specific (rather than Tegra-wide)
functionality to be implemented without the core Tegra code needing to be
aware of the details. While board186.c is currently only used for
Tegra186, it should be applicable to any other future SoC, and perhaps its
simple design could be back-ported to older SoCs in the future too.

This series logically relies on the DWC EQOS driver series that I just
sent in order for the device to actually work. However, the code should
compile and even run (albeit without yet enabling Ethernet) even without
both series applied. So, the two series don't need to be applied in any
particular order, nor in the same branch.
