drm/i915: Store backpointer to GT in uncore
We now support a per-gt uncore, yet we're not able to infer which GT we're operating upon. Let's store a backpointer for now. At this point the early initialization of the gt needs to be broken in two parts where the first is needed to assign to the gt the i915 private data pointer and the uncore. A temporary function has been made and the two parts are __intel_gt_init_early() and intel_gt_init_early(). This split will be fixed in the future with the multitile patch.
