Add i915_vma_instance_persistent() to create persistent vmas. Persistent vmas will use i915_gtt_view to support partial binding. vma_lookup is tied to segment of the object instead of section of VA space. Hence, it do not support aliasing. ie., multiple mappings (at different VA) point to the same gtt_view of object. Skip vma_lookup for persistent vmas to support aliasing.
