[Tejas Upadhyay]

Patch series introduces this in several patches,

   DUT# cat /sys/class/drm/cardX/device/gtN/engines/
   ccs/ bcs/
2. Add default entries with its value for user to go back

3,4,5 : Add individual engine properties sysfs entry
6: Introduce min/max to control in what range these properties

    - 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
