Create board configuration for peppy bringup

This change copies the slippy board configuration as a starting
point for peppy. This change is essentially the same as
https://gerrit.chromium.org/gerrit/55820

BUG=chrome-os-partner:19640
BRANCH=none
TEST=manual

Tested on slippy as there are no peppy-specific changes yet.
