Allows stolen region to track it's own reservations. - Pre-reserve first page of stolen mem (add back WaSkipStolenMemoryFirstPage:bdw+) - Improve commit descritpion for "drm/i915: sanitize mem_flags for stolen buffers" - replace i915_gem_object_pin_pages_unlocked() call with manual locking and pinning. this avoids ww ctx class reuse during context creation -> ring vma obj alloc.
