The remaining utils display needs from i915_utils.h are primarily MISSING_CASE() and fetch_and_zero(), with a couple of i915_inject_probe_failure() uses. To avoid excessive churn, add duplicates of MISSING_CASE() and fetch_and_zero() to intel_display_utils.h, and switch display to use the display utils. As long as there are display files that include i915_drv.h, which includes i915_utils.h, we'll need #ifndef guards for MISSING_CASE() and fetch_and_zero() in both utils headers. We can remove them once display no longer depends on i915_drv.h. A couple of files in display still need i915_utils.h for i915_inject_probe_failure(). Annotate this. They will be handled separately.
