Now that it doesn't need to leverage SWITCH_TASK to send the AC_CHANGE notification, pure GPIO-based external power detection can move from switch.c to its own file. BUG=chrome-os-partner:18256 BRANCH=none TEST=add AC power, UI shows charging indicator; remove AC, indicator goes away Change-Id: Id495f34185b7d971c241ac6d0a8311a6bf544507 Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/45789
