Move files in preparation for merging keyboard_scan modules

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
