We have a default context which suits the aliasing PPGTT well. Tie them together so it looks like any other context/PPGTT pair. This makes the code cleaner as it won't have to special case aliasing as often. The patch has one slightly tricky part in the default context creation function. In the future (and on aliased setup) we create a new VM for a context (potentially). However, if we have aliasing PPGTT, which occurs at this point in time for all platforms GEN6+, we can simply manage the refcounting to allow things to behave as normal. Now is a good time to recall that the aliasing_ppgtt doesn't have a real VM, it uses the GGTT drm_mm.
