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.
