This works around a problem where columns are not tri-stated when calling select_column(COLUMN_ASSERT_ALL) with enable_scanning=0. Also removes polling for power button released; we can use the same task wait for that as we do for a keypress. Signed-off-by: Randall Spangler <rspangler@chromium.org> BUG=chrome-os-partner:7486 TEST=manual 1) press g then press power button repeatedly.
