Subject: [PATCH v2 3/4] drm/i915: switch to generic header check facility

Switch to the generic header check facility, and sunset the copy-pasted
local version.

Keep the header checks gated on CONFIG_DRM_I915_WERROR as before. To be
unified later.

Reported-by: Linus Torvalds <torvalds@...ux-foundation.org>
Closes: https://lore.kernel.org/r/CAHk-=wjMrqzuUmH-mFbR_46EWEFS=bB=J7h9ABMVy56Vi81PKQ@mail.gmail.com
