drm/xe: Add sysfs entry for tile
We have recently introduced tile for each gpu,
so lets add sysfs entry per tile for userspace
to provide required information specific to tile.
V5:
- define ktype as const
V4:
- Reorder headers - Aravind
V3:
- Make API to return void and add drm_warn - Aravind
V2:
- Add logs in failure path
