This is a largely trivial set that makes vmwgfx support module reload and PCI hot-unplug. It also makes IGT's core_hotunplug pass instead of kernel oops'ing. The one "ugly" change is the "Introduce a new placement for MOB page tables". It seems vmwgfx has been violating a TTM assumption that TTM_PL_SYSTEM buffers are never fenced for a while. Apart from a kernel oops on module unload it didn't seem to wreak too much havoc, but we shouldn't be abusing TTM. So to solve it we're introducing a new placement, which is basically system, but can deal with fenced bo's.
