Matthew Brost dd157120f7 drm/xe: Add debugfs pagefault_info
Add a debugfs entry to dump Xe page fault queue state. The output
includes queue geometry (entry size, total size, head/tail), per-entry
allocation state counts, and whether each page fault worker cache is
currently valid.

This is intended to help debug page fault storms, chaining, and retry
behaviour without needing tracing.
