reef: Initial commit
This adds the basic framework for Reef including full GPIO listing,
board config file, and rudimentary functionality. It has not been
fully tested and still has several TODOs/FIXMEs. For now we just need
something that will build and can be incrementally improved.
BUG=chrome-os-partner:53035
BRANCH=none
TEST=EC and AP both boot, seems reasonably stable for now
