[CI 5/7] drm/i915: Wait boost requests waited upon by others

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

Use the newly added dma-fence API to apply waitboost not only requests
which have been marked with I915_WAIT_PRIORITY by i915, but which may be
waited upon by others (such as for instance buffer sharing in multi-GPU
scenarios).
