    drm/xe/pvc: Enable fixed CCS mode
    
    Allow static assignment of compute slices to a user selected
    number of compute engines. Add a per-tile 'ccs_mode' sysfs
    interface for user selection. By default assign all compute
    resources to the first available compute engine. User must
    ensure the tile is idle while changing the ccs mode as this
    causes a tile reset.
    
    Support this mode for PVC which can be extended to other
    platforms in future.
