broadwell: Add event log entry for GPIO27
Add event log entry if GPIO27 is used to wake the system. This GPIO is treated separately from other GPE and it is one of the only events that can wake from Deep Sx. BUG=chrome-os-partner:31549 BRANCH=samus TEST=samus: suspend/resume and wake from keypress, check for GPIO27 event in event log.
