This is part one of a series to merge the keyboard scan interface to be common across all platforms. This change just moves and renames files and APIs and removes some read code, and sets up protocol-specific CONFIG options. It makes the next CL which actually merges keyboard scanning easier to parse. BUG=chrome-os-partner:18360 BRANCH=none TEST=compile all boards; test keyboard on spring and link Change-Id: I815a40aae4e5d5f333b8501aff9656080533d913 Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/46549 Reviewed-by: Bill Richardson <wfrichar@chromium.org>
