[CI 29/33] drm/i915: Compartmentalize ring buffer creation

[Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxxxxxxxx>]

From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>

Continuing on the theme of compartmentalizing the code better to make
future split between gt and display in global i915 clearer.

v2:
 * Pass in ggtt instead of gt. (Chris)
