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.
