drm/i915: Compile-time concatenate WARN_ON macro strings
Using __stringify(x) instead of #x adds support for macros as
a parameter and compile-time concatenation reduces the runtime
overhead.
Slightly increases the .text size but should not matter.
v2:
- Define I915_STATE_WARN_ON though I915_STATE_WARN
(Bikeshed inspiration by Chris)
v3:
- More specific commit message
v4:
- Do not directly pass arbitary string as format, instead
guard with "%s" (Dave)
