[Intel-xe] [PATCH v2 7/9] fixup! drm/xe/display: Implement display support

[Jani Nikula <jani.nikula@intel.com>]

While it would be preferrable to get rid of the file altogether, in the
mean time rename ext/intel_device_info.c to ext/i915_utils.c to better
reflect what it's about.

v2: Rebase, retain __i915_inject_probe_error()
