Jani Nikula bb6a498568 drm/i915/utils: drop unnecessary ifdefs
The i915_utils.h and intel_display_utils.h were in some cases included
from the same files, the former via i915_drv.h and the latter
directly. This lead to a clash between MISSING_CASE() and
fetch_and_zero() defined in both, requiring ifdefs.

With the display dependency on i915_drv.h removed, we can also remove
the now unnecessary ifdefs.
