    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.
