This function accepts a timeout value of -1, so add a comment to that effect. Also make it deal with this explicitly since the current function seems to return prematurely in that case. BUG=chrome-os-partner:9424 TEST=very ad-hoc: 1. build and boot on daisy, flash U-Boot with USB using 'cros_bundle_firmware -w usb', inserting daisy USB cable when it says 'Reseting board via servo...' 2. Press cold reset, then power on, see that it powers on 3. Then hold power-on for 8 seconds and see that it power off 4.

This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.
