broadwell: Clear pending GPE events before entering sleep state
In the case of an EC wake event that is pending but not cleared it is possible for the EC wake pin (i.e. GPIO27) to be asserted after the kernel triggers the sleep SMI but before the system goes to sleep. If this happens then the GPE will be reported as a wake source when the system wakes up again. BUG=chrome-os-partner:33218 BRANCH=samus,auron TEST=build and boot on samus, use the keyboard to enter suspend with suspend_stress_test and ensure that only the RTC is listed as a wake source upon resume.
