i915/gem_exec_suspend: Exercise S0 (aka s2idle)
Exercise the first level of suspend, S0. This is basically the same as
our runtime-suspend, we need to put the device to sleep but otherwise
it is left powered up.
Ideally, we would measure the energy consumption in this state.
Maybe /sys/class/power_supply/BAT0/* can be of some value.
