Add initial support for Oak rev1 board. This is just the EC and includes battery charging but does not include USB PD. BUG=none BRANCH=none TEST=load on oak board and get console Signed-off-by: Rong Chang <rongchang@chromium.org> Signed-off-by: Alec Berg <alecaberg@chromium.org> Change-Id: I626f3921025fbc39ba22b04eeb6dd1084cd70777 Reviewed-on: https://chromium-review.googlesource.com/261678
