[Intel-gfx] [PATCH 16/20] drm/i915/gt: Drop stale commentary for timeline density

[Chris Wilson]

We no longer allocate a continguous set of timeline ids for all engines
upon creation, so we no longer should assume that the timelines are
density allocated within a context. Hopefully, still dense enough for us
to take advantage of the compressed radix tree.
