The interrupts to detect when the falling edge on the UART signals are currently disabled and never reenabled. Power off is detected by polling and not through interrupts. This change removes all of those falling edge interrupts. BUG=none BRANCH=none TEST=cr50 can detect when the EC, AP, and Servo are off or on Change-Id: I0fd8a0d970f3235b26af6b90dd395ea7c75e0c17 Signed-off-by: Mary Ruthven <mruthven@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/385192 Reviewed-by: Bill Richardson <wfrichar@chromium.org>
