Remove copied code from V1 implementation, reduce to bare minimum needed to satisfy external dependencies. Don't actually enable it for any platforms, though. BRANCH=ToT BUG=chrome-os-partner:23776 TEST=make buildall -j It's used by anything and doesn't do anything if it was, but test compilation of the changed sources by defining CONFIG_CHARGER_V2.
