Subject: [PATCH] drm/i915: Add Sphinx-compatible references to struct fields

This fixes the following kernel-doc warnings and makes the corrsponding fields
show up in the generated HTML:

./drivers/gpu/drm/i915/i915_drv.h:1143: warning: Incorrect use of kernel-doc format:          * State of the OA buffer.
