This was pretty handy when figuring out what exactly went wrong with ppgtt and it might also be useful when we stop filling the entire gart with scratch page entries. Also add the gen6+ DONE reg while at it. v2: Chris Wilson suggested to allocate the error_state with kzalloc for better paranoia. Also kill existing spurious clears of the error_state while at it.
