Chromebook C201 (codename veyron_speedy) support

This introduces Libreboot support for the Asus Chromebook C201 (codename
veyron_speedy). At this point, this produces a standalone Libreboot image that
can be flashed to the RO Coreboot partition of the SPI flash, as well as the
Libreboot version that can be flash to the RO Firmware ID partition.

Libreboot on the Chromebook C201 uses the depthcharge bootloader, modified to
display text messages instead of ChromeOS bitmaps (that encourage the use of
ChromeOS).

For convenience, an installation script, chromebook-flash-replace, is provided
along with a description of the flash layout, to ease the replacement of the
Coreboot and RO Firmware ID partitions on the full SPI flash image.
