Had a quick discussion with Imre on irc, and yes this is fine. Though we
could move gem_init_stolen even earlier, into i915_gem_gtt_init() or
just after. I favour gtt_init since the stolen arena is closely coupled
with the gtt probing in i915_gem_gtt_init().

Also intel_setup_mchbar() is semantically related to our
dev_priv->regs = pci_iomap(), and I would suggest a new
intel_setup_mmio() to do both, nice and early.
