hammer: Pulse detection pin on USB wake event
When usb_wake is called (key press, trackpad event), pulse
detection pin for 100us. This allows Lid EC to wake the AP
even when it is in deep S3 mode, where normal wake using USB
lines does not work.
BRANCH=none
BUG=b:35775062
TEST=Flash hammer, looks at poppy console: base power is not
disconnected, but events appear in the console.
