[U-Boot] [RFC PATCH 3/3] tegra2: Add support for Paz00 (Toshiba AC100)

The Toshiba AC100 (code-name Paz00m a/k/a Dynabook AZ) is an netbook derived
from the NVIDIA Tegra Harmony reference board. It ships with Ubuntu, but is
often repurposed to run Linux. This patch adds just enough support to get a
U-Boot serial console, and the ability access built-in eMMC and the external
SD slot.
FIXME: Since this board is not marketed by NVIDIA (Toshiba is the vendor, and
Compal the ODM), this board should possibly be moved out of the board/nvidia
directory.
