    broadwell: Turn off panel backlight in S5 SMI handler
    
    In order for some panels to meet spec when the system is put
    into S5 by way of power button during firmware (i.e. not by
    the OS) then it needs to turn off the backlight and give it
    time to turn off before going into S5.
    
    If the OS properly sequences the panel down then the backlight
    enable bit will not be set in this step and nothing will happen.
