[PATCH 0/5] drm/xe: Fix mismatched include guards in header files

[Shuicheng Lin <shuicheng.lin@intel.com>]

Mostly generated by AI and reviewed to confirm the change is correct.


Audit and normalize include guards across 24 xe driver headers to follow
the dominant _XE_<BASENAME>_H_ convention used by ~232 of ~260 xe headers.

The series is organized from most severe to least:

1. Add missing include guards to 2 completely unprotected headers
   (xe_dep_scheduler.h, xe_pcode_api.h) that could cause duplicate
   definition errors on multiple inclusion.
2. Add missing _H suffix to 10 headers using _XE_<NAME>_ guards.
3. Add missing trailing underscore to 4 headers using _XE_<NAME>_H.
4. Add missing leading underscore to 2 headers using XE_<NAME>_H_.
5. Normalize 6 headers from __XE_<NAME>_H__ double-underscore style
   to single-underscore, avoiding C reserved identifiers (C11 §7.1.3).

No functional changes. Compile-tested only.
