[PATCH 02/33] drm/i915: Introduce struct intel_gt as replacement for anonymous i915->gt

[Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com>]

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

We have long been slighlty annoyed by the anonymous i915->gt.

Promote it to a separate structure and give it its own header.

This is a first step towards cleaning up the separation between i915 and gt.
