drm/xe/xe_bo_move: Enhance xe_bo_move trace
Enhanced xe_bo_move trace to be more readable. It will help to show the migration details. Src and dst details. v2: Modify trace_xe_bo_move(), it takes the integer mem_type rather than a string. Make mem_type_to_name() extern, it will be used by trace.(Thomas) v3: Move mem_type_to_name() to xe_bo.[ch] (Thomas, Matt) v4: Add device details to reduce ambiquity related to vram0/vram1. (Oak) v5: Rename mem_type_to_name to xe_mem_type_to_name. (Thomas) v6: Optimised code to use xe_bo_device(__entry->bo).
