drm/i915/ringbuffer: Use the HEAD auto-reporting mechanism My Sandybridge only reports 0 for the ring buffer registers, causing it to hang as soon as we exhaust the available ring. As a workaround, take advantage of our huge ring buffers and use the auto-reporting mechanism to update the status page with the HEAD location every 64 KiB.
