drm/i915: Implement batch and ring buffer dumping
We create a debugfs node (i915_ringbuffer_data) to expose a hex dump of the ring buffer itself. We also expose another debugfs node (i915_ringbuffer_info) with information on the state (i.e. head, tail addresses) of the ringbuffer. For batchbuffer dumping, we look at the device's active_list, dumping each object which has I915_GEM_DOMAIN_COMMAND in its read domains. This is all exposed through the dri/i915_batchbuffers debugfs file with a header for each object (giving the objects gtt_offset so that it can be matched against the offset given in the BATCH_BUFFER_START command.
