My first attempt was to use

struct i915_live_data {
	struct drm_i915_private *i915;
};

but for this pass everything is basically using i915 as the data
parameter, so went with that for a smaller patch.

It may also be interesting to a do a i915_mock_subtests() that creates
and destroy a mock_gem_device around each subtest. I am sure we will
start using setup/teardown more creatively in future :)

Also remind me to pay attention to kunit and see if we can have a smooth
transition over to a central framework.
