I really wanted to cook up some kind of tool to actually verify we don't
lose some important registers due to D3/S0ix on each platform, but doesn't
look like I'll find enough time for that anytime soon, so might as well
flip the switch and hope for the best. IVB,SKL and BXT are the only ones
missing in any case.

I won't pretend that I've reviewed this as that would require me to cook
up that tool, but I can toss in an ack.
