From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>
Having made start to better code compartmentalization by introducing
struct intel_gt, continue the theme elsewhere in code by making functions
take parameters take what logically makes most sense for them instead of
the global struct drm_i915_private.
