[Intel-gfx] [PATCH 15/51] drm/i915: Update i915_gem_object_sync() to take a request structure

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

The plan is to pass requests around as the basic submission tracking structure
rather than rings and contexts. This patch updates the i915_gem_object_sync()
code path.

For: VIZ-5115
