I don't follow. We were previously automatically disabling ASPM on
pre-1.1 devices even if _OSC didn't give us control. I've confirmed that
this was the wrong thing for us to be doing, and my patch changed the
behaviour such that if the firmware enables ASPM on a pre-1.1 device and
refuses to give us control via _OSC we will leave ASPM enabled.
