[PATCH v2 1/2] drm/xe/compat: refactor compat i915_drv.h

[Jani Nikula]

The compat i915_drv.h contains things that aren't there in the original
i915_drv.h. Split out gem/i915_gem_object.h and i915_scheduler_types.h,
moving the corresponding pieces out, including FORCEWAKE_ALL to
intel_uncore.h.

Technically I915_PRIORITY_DISPLAY should be in i915_priolist_types.h,
but it's a bit overkill to split out another file just for
that. i915_scheduler_types.h shall do.

With this, the compat i915_drv.h becomes a strict subset of the
original.
