Subject: google/veyron_mickey: Add new mainboard

This simply copies veyron_brain to veyron_mickey and makes the
minimal set of changes (s/brain/mickey) to make it compile. The
follow-up patch will take into account board differences.

BUG=none
BRANCH=none
TEST="emerge-veyron_mickey coreboot" doesn't fail
