Brain: Initial mainboard import

This adds a directory with files copied over from Jerry, in addition to
build system related changes (configs/* and Kconfig stuff) necessary
to emerge-veyron_brain coreboot.

The next patch will account for differences between Jerry and Brain.

BUG=none
BRANCH=none
TEST=emerge-veyron_brain coreboot works
