Subject: [PATCH] drm/i915/display: switch to intel_display_utils.h

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.
