When the PF is configured for admin‑only mode, it is restricted to
management functions and should not allow users to run workloads.
Suppress device capabilities to userspace in admin-only PF mode.

---
V6 -> V7:
- Allowed xe_observation_ioctl as well with admin-only PF (Ashutosh,
Michal Wajdeczko).
- Updated commit message with steps to enable admin-only mode (Rodrigo).

V5 -> V6:
- Updated commit message.
- Make content of query_engines and query_mem_regions as empty in
admin-only PF mode instead of query size as zero.
- Allow all other query IOCTLs excepts query_engines and query_mem_regions
(Michal Wajdeczko).

V4 -> V5:
- Updated commit message (Matt B).
- Introduced new driver_admin_only_pf structure (Michal Wajdeczko).
- Updated all query configs (Michal Wajdeczko).
- Renamed xe_device_is_admin_only() to xe_device_is_admin_only_pf()
- Fixed other review comments (Michal Wajdeczko).

V3 -> V4:
- Suppressed device capabilities in admin-only PF mode. (Wajdeczko)

V2 -> V3:
- Introduced new helper function xe_debugfs_create_files() to create
debugfs entries based on admin_only_pf mode or normal mode.

V1 -> V2:
- Rebased to latest drm-tip.
- Update update_minor_dev() to debugfs_minor_dev().
