Patch series introduces this in several patches,
1. Add basic directory engine class under its GT, as below
   DUT# cat /sys/class/drm/cardX/device/tileN/gtN/engines/
   ccs/ bcs/
2. Add default entries with its value for user to go back
   to default
3,4,5 : Add individual engine properties sysfs entry
6: Introduce min/max to control in what range these properties
   can be set for elevated and non-elevated users.

VLK-46764, VLK-46767

V8 :
   - Modify enforce_sched_limit logic - Niranjana
   - make sure min < max - Niranjana
   - Push all errors to common err path - Niranjana
V7 :
   - access engine class interface inplace of hw engine - Niranjana
   - Use some API to lower down duplication of code
   - Return EINVAL in place of EPERM
V6 :
   - Scheduling props should apply per class engine not per hardware engine - Matt
   - Do not record value of job_timeout_ms if changed based on dma_fence - Matt
   - Removed timeout validation check as range validation covers it
   - Rebase all the patches based on above changes
V5 :
   - Rebase to resolve conflicts - CI
V4 :
    - Rebase the series
    - Add CONFIG option to enable/disable min/max limitation on
      elevated user - Matt/Joonas
    - Movement of engine related code to its own file
V3 :
    - Improve class_mask logic
V2 :
    - Rebase to solve conflicts
    - Use sysfs_create_files in this patch - Niranjana
    - Handle prototype error for xe_add_engine_defaults - CI hooks
    - Remove unused member sysfs_hwe - Niranjana
    - Restric min/max setting to #define default min/max for
         elevated user - Himal
    - Remove some unrelated changes from patch - Niranjana
