[Intel-gfx] [PATCH 01/10] drm/i915: Add i915 device based MISSING_CASE macro

[Pankaj Bharadiya]

Now that we have struct drm_device based drm_WARN, introduce struct
drm_i915_private based i915_MISSING_CASE macro which uses drm_WARN so
that device specific information will also get printed in backtrace.

i915_MISSING_CASE macro should be preferred over MISSING_CASE,
wherever possible.
