tegra2: Add support for Compal Paz00 (Toshiba AC100)



The Toshiba AC100 (Compal code-name Paz00, aka Dynabook AZ) is a netbook
derived from the NVIDIA Tegra Harmony reference board. It ships with
Android, 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.

v2:
* Rebased on latest HEAD, incorporated changes made to other board files.
* Moved board files from board/nvidia to board/compal.
* Switched to correct odmdata value. This required add the previous patch
  to fix U-Boot's interpretation of the odmdata RAM size field.
* Removed nvmem= from default Linux kernel command-line; no drivers use the
  reserved memory yet, so there's no point reserving it.
