[Marshall Dawson (Code Review)]

Hello build bot (Jenkins),

I'd like you to reexamine a change.  Please visit

to look at the new patch set (#3).

Change subject: google/kahlee: Add ChromeOS and ChromeEC
......................................................................

google/kahlee: Add ChromeOS and ChromeEC

Add the basics for building as a ChromeOS device. ChromeOS
and ChromeEC are dependent on each other, so bring them in
together. The EC is a Nuvoton and you can find additional
details in the Chromium EC repo.

The chromeos.fmd for Kahlee takes advantage of the AGESA
located outside cbfs and includes typical RW, VPD, and
MRC areas.

There are some updates required to depthcharge, vboot, GPIOs,
and the ChromeEC before we have a complete-ish system.
