HW guys say that it is not a cool idea to let device
go into rc6 without proper 3d pipeline state.
For each new uninitialized context, generate a
valid null render state to be run on context
creation.
This patch introduces a skeleton with empty states.
v2: - No need to vmap (Chris Wilson)
- use .c files for state (Daniel Vetter)
- no need to flush as i915_add_request does it
- remove parameter for batch alloc size
- don't wait for the init (Ben Widawsky)
v3: - move to cpu/gpu (Chris Wilson)
