The ppgtt page directory lives in a snatched part of the gtt pte range. Which naturally gets cleared on hibernate when we pull the power. Suspend to ram (which is what I've tested) works because despite the fact that this is a mmio region, it is actually back by system ram. Fix this by moving the page directory setup code to the ppgtt init code (which gets called on resume). This fixes hibernate on my ivb and snb.
