Only link actually used this function, but all batteries were required to provide an (empty) implementation. Use CONFIG_BATTERY_VENDOR_PARAMS to gate this functionality, so non-link battery code can be simpler. BUG=chrome-os-partner:18343 BRANCH=none TEST=build all platforms and pass unit tests Change-Id: Ic2c6dd1163a981e48873d798f77891cc7de1f8cf Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/65257 Reviewed-by: Bill Richardson <wfrichar@chromium.org> Reviewed-by: Rong Chang <rongchang@chromium.org>
