[Intel-gfx] [PATCH 23/25] drm/i915: Move i915_gem_init_contexts() earlier

[Chris Wilson]

As the GEM global context setup is now independent of the GT state
(although GT does currently still depending upon the global
i915->kernel_context), we can move its init earlier, leaving the gt init
ready to extracted.
